In my past life, I signed a marriage agreement, served as a live-in son-in-law for five years, and died in a hospital. Meanwhile, my "wife," Grace, was on the moon, embracing her lover and watching the star rings.
Given a second chance, she threw the agreement in my face at the marriage summit: "Sign it. After the wedding, I'll go find Karl. You'd better act like the legal wife."
I didn't refuse; I just tossed the agreement to my emotional nemesis .
The whole city laughed at my madness.
Until Grace flaunted her "pure-blood heir" at the 100-day celebration, I publicly projected her sterilization report—

And her lover was being mutilated in the downtown area.
In this life, I'm not a live-in son-in-law; I'm her gravedigger.

For three years of marriage, I played the perfect, obedient wife.
I married him only because my family once saved his from bankruptcy, and because I had loved him since college.
I thought time would soften his heart.
Then his ex returned, and everything fell apart.
He threw a welcome party for her himself, called me to the office under the pretense of work, then turned around and dismissed me as an eyesore. The whispers in the company cut into me like needles.
That same day, the hospital called. I was eight weeks pregnant with his child. Before the joy could settle, the word divorce fell lightly from his lips.
I asked for three months, just enough time to leave with what little dignity I had left. He agreed without emotion.
Yet after I moved out, he secretly placed me in a luxury apartment and stationed people to watch me day and night.
When I finally hid my pregnancy and resolved to raise the child alone, ready to confront his scheming ex, he cornered me against the wall, eyes red, voice shaking.
“Who gave you permission to walk away with my child?”

A wealthy heir was ordered to seduce me, intending to photograph me in compromising positions to destroy my reputation.
At midnight, his hands trembled as he prepared to send the photos, but I coldly exposed his cowardice and ambition.
That night, he deleted all the evidence before my eyes, his gaze filled with complete fanaticism and submission.
Later, he knelt on one knee with a diamond ring, but I poured myself a drink: "I don't need a partner to share power with—I just need an obedient dog."

As the most cold-blooded and ruthless Mafia don, Twain Hall had doted on me like the apple of his eye for ten years.
But on the very day we were discussing our wedding, the ring his subordinate delivered had another woman's name engraved on it—not mine.
I pretended not to notice and turned to Twain.
"Did they bring the wrong ring? Who's Dorothy? I've never heard of her."
Twain's expression didn't change. He pulled me into his arms with that familiar, indulgent look.
"My people weren't careful. Made a fool of themselves."
"I'll have them exchange it right away. Can't keep my queen waiting."
I smiled. But the moment I turned away, my face went cold. I dialed a number.
"Didn't you say you'd pay any price to marry me? Twain Hall betrayed me. I want his head!"
