High school student Jugyeong is bullied at school just because she is ugly. One day she goes to the rooftop, but a man saves her, thinking she was suicidal. Meanwhile, she has to move houses because of her father.

Jugyeong encounters Suho with no make-up at a comic book store. Meanwhile, during her first day of her new school, she becomes popular with her make-up. However, she is anxious Suho will find out about her true face behind her make-up.

Suho saves Jugyeong who almost exposes her true face. As a result, Jugyeong shows Suho her true face and tells him everything, and she becomes his errand-girl. Meanwhile, Seojun tells Jugyeong to return his helmet.

Suho and Seojun fight, and the school thinks they fought because of Jugyeong. Meanwhile, Seojun notices that Suho likes Jugyeong, so he deliberately approaches Jugyeong.

Seojun approaches Jugyeong to annoy Suho, and Suho keeps his distance with Jugyeong to protect her. Meanwhile, Jugyeong sees a junior getting bullied just like her, so she helps her.

Jugyeong is confused at Suho's cold attitude, and Suho feels sorry for Jugyeong. Meanwhile, Jugyeong and Seojun become closer. However, Jugyeong soon encounters students who used to bully her.
