Chanyeol is one of those guys in school who all the girls want. 

Well, look at him, who wouldn't love that baby-face adn that deep voice of his.

Well, there is one girl at school who doesn't seem to like him. 

But that's not who this story is about, it's about how Chanyeol's priorities in girls changed after he met her sister. 

Can Chanyeol change from the school's heartbreaker to a loving boyfriend?
