She thought it was nothing more than a one-night mistake — not knowing she had long since become an obsession he couldn't shake.

Emily was just an ordinary woman, yet she stumbled into Evan's world by chance. He was cold, domineering, and untouchable — and yet, time and again, he lost control in front of her. He said he needed to restrain himself, yet he appeared at her most vulnerable moments again and again. He said he felt nothing for her, yet in the instant she trembled and broke into tears, he gently pressed his forehead against hers — "I'll admit it. What I feel for you is different."

But who, exactly, was the "you" he spoke of?

Her name, her body, every sound she made — he said they were identical to someone else's.

Was she a substitute? Or the one he truly wanted, buried somewhere deep inside him?

As desire and secrets became entangled, as the closeness of flesh could no longer silence the questions in her heart, Emily began to realize — this man's reasons for drawing near to her may never have been impulse alone, not from the very beginning.

"Are you really Emily?"

"Riccardo, please! I beg you!"
My water broke ten minutes ago. Warm liquid streamed down my legs and slowly froze into ice on the ground beneath me.
He stood on the other side of the bulletproof glass. In his eyes, there was not a trace left of the man I had once loved with all my heart.
In the Bellanona Mafia family, bloodline surpasses everything, and the hierarchy of age is an unyielding iron rule: the firstborn son shall inherit the entire underworld empire.
My sister-in-law Sofia and I were both pregnant, our due dates merely one day apart.
To make sure his elder brother’s child seized the succession right first, my husband coldly chose to sacrifice our own flesh and blood.
"My brother’s child must be born first." Riccardo’s voice came over the intercom, colder and more piercing than bitter winter wind. "This is what you owe them."
He had not only locked me inside this icy cellar. Just moments ago, his men pinned me down ruthlessly and injected a dose of medicine into my vein, solely to forcefully halt my labor.
Writhing in agony, I hugged my heavily pregnant belly tightly with both arms.
I could distinctly feel the little life inside me, once kicking and struggling relentlessly, growing fainter and fainter.
I’m sorry, my baby… Mommy is so sorry for you.

Luna has tried her best to make her forced marriage to Xen work for the sake of their child. But with Riley and Sophia- Xen's ex-girlfriend and her son in the picture. She fights a losing battle.
Ollie, Xen's son is neglected by his father for a very long time and he is also suffering from a mysterious sickness that's draining his life force.
When his last wish to have his dad come to his 5th birthday party is dashed by his failure to show up, Ollie dies in an accident after seeing his father celebrate Riley's birthday with Sophia and it's displayed on the big advertising boards that fill the city.
Ollie dies and Luna follows after, unable to bear the grief, dying in her mate's hands cursing him and begging for a second chance to save her son.

But this time around, Luna is willing to get rid of everyone and anyone even her mate if he steps in her way to save her son.

"I need a fake fiancée for three months. You live here. You attend events with me. You pretend to be madly in love with me, and you annoy my grandfather by simply existing. In return, you get this check today, and another one for the same amount when the contract ends."
He took a step closer. I could smell the champagne on him, sweet and sharp.
"So, Andrea Rostova," he said, holding the check out to me. "Do you want to go back to washing dishes and drowning in debt? Or do you want to play a game with me?"
Desperate to save her sick mother, Andrea agrees to become billionaire Maxwell Harrington's fake fiancée. What begins as a simple contract soon turns into something far more dangerous as fake kisses become real feelings.
But Maxwell's jealous ex manipulates him into believing Andrea betrayed him for money, and he cruelly throws her away.
Pregnant and heartbroken, Andrea disappears.
Four years later, Maxwell discovers the daughter he never knew existed. Determined to reclaim his family, he forces Andrea back into his mansion with one ruthless ultimatum: return to him for six months, or lose custody forever.
Now Andrea must decide if the man who destroyed her heart can truly become the man willing to protect her at all costs.

I can't believe My dad will kick me out of my family to be a rouge. The werewolf world is very competitive but I never expected it to be this brutal from the moment I left my old pack border, it felt like deaths would befall me if I were a Rouge. It continued until I was half alive in the territory of another pack. Since I am a rouge trespassing is punishable by death but what if the alpha of this pack it's my mate .....?
Angus, Alpha of the crosswood pack. He is ruthless, cruel fierce, and a dominant wolf whose name strikes fear in the heart of other alphas because of his incredible strength and undeniable courage. When Angus found his mate in his territory, he was excited until he found out that she was a Rouge.

"I, Kiara Vane, reject you, Alpha Liam!"

Kiara was the Westland Pack’s greatest joke: a blind, wolfless Luna married to a man who loathed her very existence. Pushed to suicide by her own twin sister’s betrayal and her mate’s cold-blooded cruelty, she was meant to be a forgotten footnote in history.

But the history books lied.

Cassandra, a feisty 21st-century student with a sharp tongue and a heart of steel, finds herself sucked into the cursed pages of an ancient text. She wakes up in the past, inhabiting the body of the "Dead Luna" under a blood-red moon.

But there’s a catch: this version of Kiara can see. And she isn't crying for mercy anymore.

Alpha Liam is a monster who swore to destroy the pack's traitors to avenge his mother’s death. He expected a broken, sightless girl he could easily crush.

Instead, he finds a defiant queen who looks at him with mockery instead of longing… a woman who seems to know his secrets before he even speaks them.

As Cassandra navigates a world of silver blades, ancient witchcraft, and a mate bond that burns with a dangerous new hunger, she has only one goal: make them all pay.

But as the "wolfless" girl begins to show the heart of a dragon, the predator slowly becomes the prey.

Liam is no longer looking for revenge… he’s looking for the woman who stole his soul.

But one question haunts the entire pack:

If the real Kiara died that night under the red moon… then who… exactly… is the woman wearing her face?

Sophie Ashford's perfect life shattered at her husband Ethan’s 35th birthday party. In front of everyone, he announced their divorce, accused her of being the reason for their childlessness, and revealed his engagement to her best friend, Veronica who is already pregnant for him. Humiliated and heartbroken, Sophie fled, vowing never to look back.

A chance encounter with Lucas Ashford, a mysterious stranger at a bar who she didn't know his name at that time, led to a one-night escape that changed everything. Weeks later, Sophie discovered she is pregnant, giving her the strength to rebuild her life at least for the sake of her child.

Four years later, Sophie had finally found peace until Ethan reappeared, claiming her son was his and begging for forgiveness. But Ethan wasn’t the only one determined to claim Sophie’s heart. Lucas, the man from the one-night stand, returned and learned the truth, that the child was his. To complicate matters further, Lucas turned out to be Ethan’s estranged cousin.

As Sophie became caught in a fierce love triangle with two brothers, Will Sophie forgive Ethan’s betrayal for her sake? Can Lucas prove his love is genuine? Or will Sophie choose herself and carve out a new path free of these men?

I was the reincarnation of the Ancient Star God and the fated mate of the Obsidian Dragon King, Ignis.

For seven years, I nearly bled my divine blood dry to break his curses. Everyone knew I loved him unconditionally.

Until his cold sneer shattered it all.

"Seraphina has laid my egg. After the Hunting Festival, I'll crown her as my queen. Keep Elara around to placate the Alliance. She's so madly in love with me, she'll gladly be a shield for them."

Something snapped deep within my chest. My empathy veins—the very magic that bound my emotions to him—shattered.

No heartbreak. No hysteria. That suffocating love was erased in an instant. Looking at Ignis now was like looking at a worthless stone.

I calmly returned to the temple and activated the marriage decree sent by the Elven High King, Aurelius.

The realm portal was charging. Departure: three days.

Billionaire. Revenge. Second Chance. Escape while pregnant.

When Mellow Fanning married Zeath Lupin, the cold chairman of Lupin Group, she thought their love was forever. But everything crumbled when he introduced his pregnant mistress at a family dinner.
Angry, Mellow sought to make Zeath restless by kidnapping the mistress. However, that resulted in a tragedy that nearly claimed her life and that of the child growing inside her—a child Zeath didn’t deserve.
She faked her death and ran away, bound to return as Zeath’s only means to remain as the chairman of Lupin Group.
Would he recognize her? Would she accept his apology if he ever gave one? And what would happen when the threat she once fled from rekindled, endangering her and her child’s lives once more?











“Do you know how much I wished you wouldn’t come near me, or even... touch me?” Zeath drones on. “All those cuddles and kisses, all the affection, made my skin crawl—like a troll embracing its victim before gobbling them. One can only imagine how much it stinks. You are no different from that troll. You merely caught my attention because you were a self-absorbed twonk, and we needed to test if you even had the heart to love another.”
“We?” I croak out.
Then Zeath’s fingers trail gently along my face, his eyes glinting with pure poison, and his voice is no better.
“Poor Mellow, it is all a dare, a gratifying one. Divorce or not, it’s your choice.”

In the delivery room, several nurses pinned me down on the operating table.

They were going to forcibly take my eight-month-old baby out of me.

The pain was tearing me apart. I locked my eyes on my husband Xavier Davis, who was standing to the side, and screamed at him in a hoarse voice.

"You animal! That's your child too. How can you do this to him..."

Xavier stared at me, his face completely blank. He didn't say a single word.

"Hurry up! Mia needs the cord blood!"

Julia, standing next to Xavier, snapped impatiently at the doctor.

She was Xavier's stepmother, only two years older than him. Her husband had died not long after she got pregnant, and Xavier had been taking care of her ever since.

Recently, Julia's one-year-old daughter was diagnosed with leukemia. She needed a newborn's cord blood for a transplant, so she set her sights on my baby.

And Xavier agreed to it. That was when I found out the two of them had been sleeping together for a long time.

Julia had nearly bled to death giving birth to their daughter, and lost any chance of having another child.

"What's going on? Her water already broke. Why isn't the baby coming?" The doctor was sweating with anxiety.

Julia picked up a pair of scissors and handed them to the doctor, her voice completely casual.

"Just cut open her uterus. Then the baby comes out."

My eyes went wide with shock. I shook my head desperately. "No. Please, no..."

She baked his pack to perfection for five years, only to overhear she was just the “cheaper version” of his fated mate.

When Alpha Brian slaps her, abandons her in flames, and chooses the villainess who faked everything… Angela walks away, rejects him forever, returns home as the hidden heiress of a powerhouse pack, marries the Lycan King who worships her and watches her ex spiral into madness.

I found my husband's vasectomy certificate while sorting medical bills. The procedure was done a year ago. But I was six months pregnant now.

I stared at the date on the paper and my hand just... stopped. I kept checking it again and again, but it was still the same. I was freaking out. I looked down at my bump showing through this baggy sweater, and my hands started shaking.

I got in my car and drove straight to my husband's private club. I needed answers about this, now.

My husband handed me divorce papers at 2 AM—right after he'd had his way with me. Three years of marriage, and he never once believed I was anything but a scheming woman who trapped him. He said he wanted his real love back. I said I wanted our daughter.
He laughed and told me I couldn't afford to raise her alone.
He was right about one thing: I needed money. So I took the only job that could change everything. He showed up at the presentation as the client. When he saw my work, his face went pale. He accused me of plagiarizing a famous designer—the very genius who had saved his company years ago.
He has no idea.
That genius is me.
And he's about to find out exactly who he just let go.

The stepbrother I grew up with was a golden boy, a star varsity quarterback everyone had high hopes for.
But for a street-level delinquent, he abandoned his Ivy League future.
Desperate to pull his life back on track, I tried to expose his toxic girlfriend.
Yet, he hated me to the bone for it.
For her, he ruthlessly dragged our family into the crossfire of a deadly gang dispute, causing us all to meet a violent, tragic end.
I never expected fate to rewind the clock.
To give me a second chance.

On my twenty-fourth birthday, my grandfather dropped the bombshell: I was an orphan.
After learning about my biological family, I decided to do something nice. I bought a limited-edition sports car as a gift for the father I had never met.
But at the dealership, I was publicly humiliated by my brother's mistress.
To clear up the misunderstanding, I called my brother.
When he arrived, it was only to back her up.
"This birthmark is ugly; let me help you get rid of it."
My own brother used a cigar to burn off the birthmark behind my ear and had my suffering broadcast on the mall's LED screen.
"Listen, if anyone dares to treat this woman’s injuries, I’ll have their license revoked in this city for good!"
But he didn’t know that the grandfather who raised me was someone no one in this city could even dream of looking up to.
When my grandfather arrived with a top-notch medical team and armed mercenaries, sealing off the entire building, my arrogant brother finally realized his mistake.

On our seventh wedding anniversary, my Alpha husband missed the candlelit dinner for the seventh time.
He rushed off to rescue an Omega surrounded by vampires, leaving me alone in the villa.
That same night, a jarring photo spread through the pack.
Damien, covered in blood, held Rose tightly in his arms, his lips pressed against her forehead.
Everyone was waiting for me to be jealous, to rage.
But I didn’t scream or argue like I used to.
Instead, I poured out his favorite champagne, closed my eyes calmly, and prayed to the Moon Goddess.
“You once said I have a destined mate.”
“If he will make me strong and free me from this wretched marriage, let him come for me in seven days.”

As the Chief Delta of Alpha Hunter and his secretly married wife, Kara had always hoped that her dedication would eventually win his heart.
However, everything changed when that rogue girl—Maya—appeared. She is Hunter's Fated mate.
According to their pre-marriage agreement, once Hunter finds his true mate, their marriage will be over.
Just then, Kara discovers that she's pregnant...

Emerald thought that she and Jace Higginson were divorced. After five years, she returns to the country to collaborate with his company and eventually takes her revenge. What will she do when she sees a different Jace, making her uneasy whenever they meet? What would she do when her supposed ex-husband was still her husband because he didn't file the divorce? Will Emerald give Jace his rights to their son whom she conceived before she left?

During a police operation to pursue a serial killer, my father-in-law was taken hostage by the criminals while protecting me, and was dragged behind a vehicle for several kilometers.
I urgently called my husband for help: “Cedric, Dad has been taken hostage by the criminals. Send more people right away!”
My husband was the police department’s top marksman—only his sharpshooting skills could target the enemy and save his father!
But to my surprise, my husband just sneered, “Dahlia, I’ve only been out with Nalisa for an hour. To win my attention, you’ll make up any lie, won’t you?”
Hearing the call end, I was frozen in shock.
Then, I received a message from Nalisa with 99 bed photos of her and my husband.
“Cedric says, if your dad dies, so be it. He has no time for you now—he’d rather die in my arms.”
Anger and sorrow enveloped me. Watching my husband’s father crushed to death by the vehicle, I finally understood:
He must have thought it was my father who was taken hostage.

In order to prolong the life of my supposedly sick "white moonlight" (my love interest), my wife forced me onto the operating table and removed my kidney while I was still alive.

To force me to leave with nothing, she even cut off my mother's medication, coldly declaring, "Your mother is just a liability that deserves to be optimized."

She thought I would wag my tail and beg for mercy like a stray dog.

Little did she know, suffering from single kidney failure, I transformed myself into the deadliest viral code before my death, dragging her business empire and that male mistress into an inescapable hell.

On the day the truth came to light, the once-powerful tech queen went completely mad. She squandered her fortune, kneeling in the frost of the morgue, kowtowing and weeping blood, begging me to look at her one last time. But she couldn't find a single hair of mine.

Because I had already made a will, ordering my remains to be cremated as high-risk medical waste.

She treated me like dirt when she was alive, and after she died, I found her disgusting and didn't even bother to leave her a handful of ashes.

Twenty years ago, he took the blame for my murder, was branded with the Silver Flame mark, and banished to the wilderness. Twenty years later, I escaped from a prison-like marriage and searched the world for him. He wasn't there in the Alaskan blizzards. He wasn't there in the deep mountains of Romania. Under the polar night in the Arctic Circle, I called his name into the darkness. No one answered. Until a hunter told me: deep in the Yukon, someone had seen a lone wolf with the Silver Flame mark.

He married me because I look like her.
For three years, I played the role. I cooked his meals. I warmed his bed. I smiled when he forgot my birthday. I stayed quiet when he left in the middle of the night to hold her hand.
I told myself it was enough. I told myself I didn't need his love.
Then I got pregnant.
He said he hated children. So I didn't tell him. I was going to keep it. Our baby. The only thing that was truly mine.
But my body had other plans.
When I called him from the hospital floor, bleeding out, begging for help—he didn't come. He said I was lying. He was too busy with her.
That night, I lost everything.
The baby. The hope. The lie I'd been living.
Now he's calling me. Again and again.
But the substitute wife? She's not picking up.

I endured in silence for five years, and everyone treated me like worthless trash. My wife sacrificed our daughter for vanity, my in-laws called me bottom-tier scum, and a senator wanted me dead to divide up my fortune. They thought I was just an ant they could trample at will. Until I produced the Supreme Commander's immunity medallion, until armed helicopters hovered above the courthouse, until I forcibly hijacked the national broadcast, they finally realized what kind of existence they had provoked. I am "Night Asura"—the one man in this world who should never be crossed.

To save my cousin from a car accident, my mother, a medical luminary, used me as a "human guinea pig" for twelve years.
When I was twelve, she made me inject myself with three injections of unproven new drugs every week;
when I was fourteen, she directly shoved toxic compounds into my mouth.
When my organs were irreversibly failing and I was vomiting blood in the ICU, she coldly tossed me a payment order:
"Stop pretending to be dead. Immediately kowtow and apologize to your brother, or no hospital will admit you."
As she wished, I was forced to leave the hospital and died at her glamorous new drug launch.
Later, that high-and-mighty mother, obsessed with fame and fortune, knelt for an entire night in a snow-covered fir forest, holding my crudely made urn.
Sadly, I will never forgive her.

My name is Damian Lemaître.

In my past life, I was Serafina Camarilla's lapdog for ten years, being drained of my life, used, and squeezed dry of my last bit of value.

I opened my eyes and found myself back at the scene of the blood pact ceremony. She sat on the high seat, waiting for me to kneel down and swear the oath with the same excitement as in my previous life.

"Damian Flamel, are you willing?"

"No."

He was born into extraordinary wealth, admired by all.
Until the woman he loved betrayed him. After years together, they parted ways.
Five years later, their paths crossed again. He sat at a bar with another woman in his arms, but the moment he saw her, rage flashed in his eyes.
"You betrayed me. What gives you the right to show your face here?"
She nodded and walked away.
He lost his mind searching for her.
Only then did he learn why she had really left.
He pulled her close, arms tight around her. "Marry me. Whatever burdens you carry, I'll carry them with you. Whatever tears fall, I'll wipe them away."

After two years of a loveless marriage, Maria Lewis was handed a cold divorce agreement. But she didn't leave quietly. She gave James Bennett one last drink, seduced him for a final night, and disappeared—secretly pregnant with his child.

Five years later, Maria returns as a powerful member of a secret organization, with two adorable kids and an identity he never saw coming. She's no longer the woman who once begged for his love. She's confident, untouchable, and completely out of his league.

Now, the man who once looked down on her clings to her, desperate to win her back.

But Maria has her own plans: protect her children, crush her enemies, and make James regret every choice he made.

She left with nothing, but returned with power, babies, and no mercy.

Seven years ago, my wife and son committed perjury in court, conspiring to send me to a high-security prison, all so they could elope with that fraudster.
Seven years later, I was released.
My ex-wife, with her son, arrogantly tossed a business card onto my faded work clothes:
"Go kowtow to my new husband and apologize, and I'll give you a waiter's job."
Little did she know that just hours later, at a top-tier financial summit across America, her seemingly untouchable new husband was kneeling at my feet like a dog.
And her proud multi-billion dollar empire was nothing more than garbage I could crush with a flick of my finger.

What if your husband lived a double life and you are the fake wife?

I woke up to my husband celebrating our baby's death. He had poisoned me with abortion pills so he could marry Catherine Morrison-the rich woman he thinks is better than me and pregnant with what he thinks is his child.

I overheard him laughing; 'if she shows up somewhere demanding answers, I'll just say I've never seen her before in my life, Who are people going to believe? Me or some random girl from nowhere?'

David thought I had no evidence. He thought he had covered his tracks perfectly. He thought he was untouchable.

But when I'm done, he'll wish he never met me.

In the apocalypse, during my escape, I awakened a useless superpower: reset .
My girlfriend, despising me as a burden who only creates junk, conspired with the mercenary captain to kick me into a horde of zombies.
She had planned everything, except for one thing.
My superpower wasn't "creating junk," but a conceptual-level divine skill !
A zombie bites my heart? Reset my body's state, instantly revived!
A rabid mutant attacks? Reset its hunger nerve, making it instantly kneel like a dog!
I single-handedly fought my way through the zombie horde and knocked on the shelter's door.
Beside the captain's shattered neck, I held my desperately begging ex-girlfriend upside down, smiling as I suspended her directly above the zombie horde.
"You were right, useless people should be zombie food. Now, it's your turn to prove your worth."
Then, I released her.

I was born the year the Rift opened. They said I would close it. They were wrong about so many things.

My name is Mia, and everything I touch is dying.

The flowers beneath my mother's window turned black overnight. The herbs I gathered at dawn rotted in my hands. When the court wizard finally told me the truth—that someone cursed me, that my presence would kill everyone I love—I realized the prophecy everyone believed was never meant to save the kingdom. It was meant to destroy me.

So I ran. Not to fulfill some destiny, but to survive it.

Now I'm traveling with a hunter who lost his companions to the same curse I carry, chasing fragments of a prophecy the Fae sing differently. An elf took a baby from the palace the night I was born. And somewhere between the lies I've been told and the truth I'm hunting, I'm starting to suspect: What if I'm not the princess from the prophecy at all?

My life took a turn for the worse when I married an arrogant billionaire who made me pregnant. Little did I know that this was just the beginning of my misery. However, a sudden and unexpected tragedy completely transformed my life, igniting a burning rage and deep contempt for him.

Believed to be dead by everyone, I have spent the past four years plotting my revenge. Returning now, my sole purpose is to make my billionaire ex-husband pay for what he did. With my own wealth, I will inflict torment upon his already debt-ridden existence.

The man I despise the most, Mr. Diego Alfonzo, is the target of my vengeance. I have vowed to myself that I will seek retribution against him.

My crave for revenge is insatiable; I yearn to witness his suffering.

"No. Everything that comes out of your mouth is a lie. Say one truth. I dare you to tell me one fucking truth."

"I love you."

"No, you don't. Say something else."

"I can't live without you."

"Shut up, you bastard! How can you say you love me when all you ever do is hurt me?"

Once a predator locks onto its prey, there's no letting go.

Leah Walsh is a lonely wife, starved for the love her husband no longer gives.
Aiden Kingston is a ruthless caporegime of the city's most feared crime family. A man who doesn't understand the word no.

She fights her attraction to him, but one reckless choice shatters her marriage and binds her to him. Now, Leah is trapped in his violent world, where simply standing by his side makes her a target for his enemies. Every attempt to escape his chains only tightens them, and Aiden's obsession grows stronger each passing day.

Will leah break free or surrender to the man who is determined to ruin her and claim her as his?

They called me Specter. The King of Assassins. The deadliest blade in the Viper Syndicate's history. I never knew fear until the day my own brother in blood put a knife in my heart and threw me off a cliff.
I should have died.
Instead, I woke up in the body of Liana Vex, the discarded, illegitimate daughter of the most powerful duke in the kingdom. A girl so broken by abuse and grief that her spirit had already faded. In her final moments, she left me one desperate wish: Make them pay.
So I made a pact with a ghost. Her pain would become my fuel. Her enemies would become my prey.
Now I walk among the nobility in a body everyone calls weak. They see a fragile girl who should have died in the gutter. They don't see the killer standing in her shadow.
My former organization thinks they buried their king. They're about to learn that dead things don't always stay dead.
My new family thinks I'm a ghost they can ignore. They're about to discover that ghosts make the worst enemies.
And then there's him, the rogue mercenary with the sharp smile and sharper blade. The only person who sees through my masks. My rival. My equal. The wolf who should know better than to chase a shadow.
They say revenge is a dish best served cold. I intend to serve it frozen, bloody, and with interest.
The Viper Syndicate took my life. The Vex family took Liana's. I'm going to take everything they have.
And this time? I won't miss it.
