One day, Kim Yeondoo, an ordinary high school girl, is suddenly terrorized by her former friend from middle school and stalker in KakaoTalk. In order to stop this, she changes her profile picture to a picture of a random guy and posts him as her boyfriend. But, it turns out that the picture she used is the school's scariest bully, Ji Hyunho?!

As it turns out, the bullies are the tsundere, Ji Hyunho, the smart and cool class president, Seo Juho, and the young man living upstairs of her home, Kang Ahun. Not only that, there's also the My Way baseball boy, Choi Seunghyun, and the pure and lively, Jung Jisung.

How did she end up getting entangled with the handsome bullies?
