Genius prodigy ​Ji Yu married the icy ​CEO Gu Yan out of gratitude, assuming their union was a temporary transaction. Wrong. While she breezed through their sham marriage, Gu Yan—her “husband-in-name-only”—quietly rewrote the rules.Post-divorce, Ji Yu thrives: clubbing with models, sipping champagne, and flaunting her freedom. ​Post-divorce, Gu Yan implodes: stalking her parties, hijacking her dates, and growling, “Try replacing me. I dare you.”But fate laughs at their feud. On the night their divorce is finalized, a reckless encounter ignites—hotter, messier, and utterly unforgettable. Now Gu Yan, the once-detached tycoon, is addicted to the wife he never truly let go.“Marry me again. Legally. Shamelessly. Forever.”“No. But thanks for the one-night souvenir, Mr. Ex.”

I had nothing left to live for.No family. No friends. No future.Just a shattered soul wandering through a world that had already taken everything.Then I died.And that’s when everything changed.I woke in a world of light. A void between realms. A place where gods whisper and broken souls wait to be judged. There, I met Ashen Crimson—a man who had once been worshipped, then feared, and finally cursed by the very gods he had defied. A tyrant who had destroyed his own world.But now, he’s offering me something terrifying:His life. His past. His power. His chance to make things right.The catch?The world of Zerawell is fractured.Ashen’s name is soaked in blood.His fate is sealed—exile, ruin, and eternal hatred.And now, it’s my name.Because I’ve been reborn as Ashen Crimson, heir to a house that both reveres and reviles me. A noble with dormant shadow magic, a shattered reputation, and a cursed destiny I never asked for.But I’ve lived a life of pain. I’ve walked alone through hell already.And I won’t follow his footsteps into madness.With a divine system familiar in my soul, a second chance burning in my chest, and the memories of a monster as my burden—I will rewrite this fate.Let them call me villain, disgrace, or traitor.I didn’t choose this story.But I’ll finish it.Even if it kills me.
