Solo and Su Cheng are each other's first love. They have been together since they were teenagers. They met because the team played a game in the Internet cafe. After a long time, they came together. Solo and Su Cheng have been in love for several years, but solo is single-minded. Su Cheng felt insecure, so he chose to break up with Solo.
Not long after the two broke up peacefully, Su Cheng accidentally discovered that she was pregnant, but at that time, the child was five months old and could not have an abortion operation. Su Cheng can't forget solo and wants to have a baby as a souvenir.
But Su Cheng's team can't make any money, and Su Cheng has no money to support Xiao Ai. After Xiao Ai fell ill, Su Cheng sent Xiao Ai to Solo, let Solo take care of Xiao Ai, and even registered Xiao Ai's marriage, and then divorced quickly.
After the divorce, Su Cheng went abroad alone, and Xiao Ai was always taken care of by Solo. However, when Xiao Ai was a child, she had a high fever and burned her ears, so she had to wear a hearing aid to hear her own voice. Solo was busy with work, and Xiao Ai's personality became very awkward. She especially hated Su Cheng.
Solo also complained about Su Cheng, but she didn't want Xiao Ai to resent her biological mother. She patiently taught Xiao Ai to respect Su Cheng and let Xiao Ai and Su Cheng live together. Xiao Ai realized Su Cheng and Thoreau's painstaking efforts.
