Three years after the breakup, she fell in love with the gentle and considerate Lu Yan and got engaged. However, she was shocked to find out at a family dinner that her fiancé's uncle was actually her ex-boyfriend Lu Chenzhou who they broke up with back then. He called her "niece-in-law" in public and was distant and restrained, but secretly he pressed closer and deliberately made things difficult for her. A family dinner tore open old love wounds, and turned her engagement party into a sadomasochistic affair that her ex-boyfriend couldn't let go of.
