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.”
