A beautiful girl who will always be 18 years old - Li Muzi (actually she is almost 20); a crazy naughty kid who is too emotional but wants to be rational; a little salty fish who has not yet found her faith and dreams. As a weak woman who can't carry her shoulders or lift her arms, she accidentally ends up in a sports school. Sure enough, if she comes out to hang out, she will have to pay back sooner or later! I still suspect that God deliberately sent me here in order to make up for the neglect and unfair treatment of sports in the past 18 years... I spent two years in a state of confusion. I wonder what Muzi will do now~ What ridiculous and crazy things are going on around her...
