Su Wan was forced to marry the wealthy young man Gu Mingzhe instead of the real daughter. On the wedding day, she accidentally discovered the groom's affair with Bai Yueguang and Lin Xuerou. She took out the divorce agreement on the spot and left the scene gracefully. Then she turned around and met the real person in charge of the Gu family - Gu Mingzhe's brother-in-law Gu Jingshen in the hotel lobby. With the words "Your nephew doesn't want me anymore, do you?", The two of them received their certificates on the same day, and Su Wan went from sister-in-law to aunt in an instant.
