At the wedding, the groom's mother publicly gives the 10,001-yuan traditional wedding tea gift, which should have gone to the bride, Shen Zhiyi, to the bridesmaid, Lin Yueran, instead. Her fiancé, Xu Mingchuan, even agrees on her behalf without asking. Shen Zhiyi immediately calls off the wedding, only to discover one shocking betrayal after another: her best friend is pregnant with her fiancé's child, and the two even expect her to raise their baby. Keeping her cool, Shen Zhiyi strikes back, making the cheating groom shoulder 500,000 yuan in wedding banquet debts and lose his job. She finally escapes the toxic relationship and finds success in both her career and love life.
