On her first visit to meet her prospective parents-in-law, Yu Sheng is subjected to all sorts of covert harassment by the family of her boyfriend Zhang Shuo, such as ill-fitting slippers, a transferred greeting gift, and a house-gifting trap. The boyfriend who should be the most trusted joins forces with the prospective parents-in-law to scheme against Yu Sheng at every turn, while the seemingly most difficult sister-in-law secretly offers help. After learning about the sister-in-law's past experience of being oppressed, Yu Sheng sees through the true face of the prospective in-laws, no longer acting as a weak and easily bullied pushover, and chooses to join forces with the sister-in-law to fight back, step by step exposing the hypocritical face of the in-laws and various tricks, ultimately waking up to cut losses, resolutely severing the seven-year relationship with Zhang Shuo, and starting her own brand-new life.
