On the day of the junior high school graduation exam of Taibin Middle School in Taibin Town, Ou Tengze accidentally made a big joke for himself. The first time Xiao Siying met Ou Tengze was the most embarrassing moment in Ou Tengze's life. Unexpectedly, Xiao Siying and Ou Tengze were in the same class when they entered high school.

Ou Tengze's feelings for Xiao Siying are getting deeper and deeper, but he doesn't know that he is Principal Xiao's daughter...
