Four best friends went to the same high school. Kim Chae-yeon, a cool girl, funniest one and the only boyish among the group. Park Seo-jung, the shy girl, who loves music and is a soft talker. Kang Eun-yeong, the hottest, badass and protective one. Izumi Sakura, the nerd, artistic, sarcastic, savage and richest one. But what happens when some of them bump into the most famous students? Who will be together to the end? What if someone tries to do something bad to them? Find out the story! (My friends requested that I have to do this story last year so, I cannot ignore them and have to manage my time.)
