As a leader, it turns out there are still things we cannot control. First, fate, and second, arranged marriage by parents. Reinhardt must marry Leonard, who is the leader of another region, to expand their territory and fulfill their parents' promise.
However, Leonard turned out to have an illicit relationship with Veronica, a friend, a confidant, who was as close as a heartbeat. Betrayal forced Reinhardt to eliminate the people around her, soothe her heartache and resentment, and heal her disbelief in someone once again. Then a man with a secret identity named Jean arrived in Reinhardt's life to become the solution.

The anonymous post’s warning came true. I was trapped in an endless loop of death.
In my first life, I took on a high-risk surgery, only to be brutally stabbed by a grieving family member afterward. Thirteen fatal wounds left me bleeding out on the floor.
In my second life, I faked an injury to avoid the operation, only to be shoved down a steep flight of stairs, resulting in extreme head trauma and a snapped neck.
In my third life, I performed the surgery alone. My reward was a cold gunshot straight through the skull.
In my fourth life, I live-streamed the entire procedure. The surgery went flawlessly, yet my throat was still slit, and my skull was crushed by a heavy blunt object.
On my deathbed, I finally glimpsed the horrifying secret hidden within the patient...

Every July, my husband left for a business trip to France—so for seven full years of marriage, we never once got to celebrate our wedding anniversary.
This time, I flew all the way to France to surprise him, and mid-flight, I stumbled across a social media post.
My dream girl finally agreed to be with me. How do I make the frumpy, worn-out wife back home file for divorce on her own?
The OP poured out his grievances in the comment section:
When my dream girl suddenly moved abroad, I married her former best friend to keep me company through the hard times, just so I wouldn’t lose touch with her completely.
Now she’s finally said yes to being with me, and I’ve made enough to give her the lavish, privileged life she deserves.
I want my wife to find out about my affair herself so I can get a clean divorce without a fight, but she’s so painfully oblivious. I’ve come home reeking of my dream girl’s perfume on purpose, and every single July I fly here to France for our private time together, watching the lavender bloom in Provence with her. She never noticed a thing.
Perfume. July. France.
Those matching details made my fingers go numb. A deafening buzz exploded in my skull. A bone-deep chill washed over me, and I prayed with everything I had that it was all just a terrible coincidence.
Until I read the final line.
Just got a spending alert from her supplementary credit card—she bought a flight to France. I’m heading to pick up my dream girl now, might as well keep an eye out for her, just in case.
The plane touched down. When I stepped into the arrivals hall, I lifted my head almost instinctively.
There stood Shen Sinian, the man I hadn’t seen in two weeks, in a crisp, tailored suit, a bouquet of roses in his hand, locked in a passionate kiss with a woman with a stunning, willowy figure, her back to me.
He opened his eyes by chance, and through the crowd of travelers, his gaze locked directly with mine.
