Wang Hao and Su Cheng have known each other since they were teenagers. At that time, they were all CTF players. These two teams often play games in Internet cafes. Wang Hao and Su Cheng have been lovers for a long time, but at that time Wang Hao only ignored Su Cheng in his heart.
Su Cheng wanted to find a boyfriend who could accompany him, not a desperate person who started the game, so he chose to break up with Wang Hao. But after breaking up, Su Cheng found herself pregnant with Wang Hao's child. Su Cheng wanted to give birth to the baby as a souvenir, so a person quietly gave birth to his daughter Xiao Ai.
But Su Cheng's team didn't get good grades and couldn't make any money. Su Cheng was unable to raise Xiao Ai and had no time to take care of the children. Later, Xiao Ai was seriously ill and had a high fever, so Su Cheng had to run to Wang Hao, but Wang Hao was already with Ai Qing.
Wang Hao adopted Xiao Ai out of duty and even married Su Cheng for a fake hukou. Su Cheng went abroad to Norway alone, and Wang Hao raised her, but the high fever burned her ears and she had to wear a hearing aid to hear it.
