Su Mengjia, a junior student at the School of Art at A University and a "socialite" from a wealthy family, initially got close to a junior student at the School of Computer Science at A University because of bets and curiosity. She is recognized as a "young and pure school sweetheart", but in fact she is dark, sensitive, extremely possessive, and has yandere traits. Li Chao included her in his "conquest list", but as they got along, he was gradually attracted by her contradictory qualities, and finally fell in love with her.
