After My Divorce, My Ex-Wife's Best Friend Suddenly Asked Me Out

Sheng Yang spent five years as a live-in son-in-law, devotedly taking care of his wife, Qi Yue, and their daughter, Nuannuan. But he unexpectedly learned from Qi Yue's best friend, Wen Yanran, that Qi Yue had not only cheated on him with his college roommate, Jiang Hongyu, but had also slept with several of his other dorm buddies. In a recording, Qi Yue herself mocked him: "He may be a bit of a loser, but he's handsome and great in bed. He's even better at looking after people than a professional nanny."

Sheng Yang decides to divorce her, but as a live-in son-in-law without a job, he has no chance of winning custody of Nuannuan. Wen Yanran proposes a deal: she'll help him get custody, and in exchange, he'll help her gather evidence that Jiang Hongyu uses and sells drugs.

Caught between his cheating wife and treacherous "brothers" on one side, and his young daughter and unknown dangers on the other, Sheng Yang steps into a perilous game. Just as he's worrying about how to make ends meet, Jiangcheng's richest man, Shen Congjun, suddenly shows up at his door. The reason? Sheng Yang has the exact same face as the Shen family's deceased son. A deal to impersonate a wealthy heir is placed before him.

Divorce, a custody battle, undercover work, a lookalike... Sheng Yang's life takes a complete turn from this moment on.
