When Zhao Qian was in high school, he was a fat boy. He had a crush on his classmate Wang Shuhao and tried his best to lose weight for him, but in the end he ended up with someone else. Zhao Qian was hit hard and eventually regained weight. After regaining weight, he lost weight again, and the cycle continued until he finally met his true love Qin Shu.
The two save each other and eventually fall in love together.
Qin Shu is a special person. Due to family reasons, he was diagnosed with paranoia since he was a child. Therefore, Qin Shu has been controlling himself not to get close to others until he met Zhao Qian. From then on, Qin Shu was only paranoid about one person in his life.
Purpose: It is too painful to have a crush on someone, so it is better to find someone to love yourself.
