Late one night, Lin Jiajia (played by Xu Mengyuan) was drugged to have a relationship with Pei Yi (played by He Congrui), the second generation of rich people, and became pregnant.After the Lin family gave birth to twins, they were told that the child had died. However, the twins were taken away by Lin Yuwei, the Lin's half-sister.On the other side, Pei Yi is also looking for the woman that night.

Five years later, the Lin family met Pei Yi, who was pregnant with twins. With the help of their children, the two got married, and the family of four began their married life.However, Pei Yi's ex-wife Jiang Xinrou, who lives abroad, was suspended from living expenses and returned to China, which hindered the relationship between Lin Jiajia and Pei Yi at every turn.Lin Yuwei framed the Lin family many times and was a pawn of Jiang Xinrou.When Lin Yuwei was no longer of use, she was abandoned by Jiang Xinrou and her legs were broken.

By chance, the stepmother of the Lin family came to Pei Yi with a video from that year and told him that the Lin family had rented a room with someone in a hotel and gave birth to a pair of children.Only now did Pei notice that the Lin family might be the person he had a one-night stand with back then.In the end, the two resolved their misunderstanding and got married.
