On their fifth wedding anniversary, Ruan Nanzhi discovers that she is pregnant with twins, only to receive divorce papers from her husband, Pei Yan—300 million dollars to buy out their five-year marriage. Xu Zhixia, his idealized first love, moves into their home and falsely claims to be pregnant. In front of everyone, Pei Yan's mother steps on the check at Ruan Nanzhi's feet. Silently, she signs the papers, picks up the check, and leaves for a distant place with her unborn children and parents. Only after Pei Yan returns does he learn the truth: the original agreement was meant to be an escape route he had left out of love, but someone secretly replaced it with an order for her to leave. The Zhizhi he has called by that name for years was never his first love. He searches every corner of the city for her, unaware that she is carrying his twins and that she conceals a shocking connection to the powerful Ruan family of Shanghai. The three hundred million was not the price of a marriage, but the beginning of a lifetime of regret he can never undo.
