Haeun and Joshua hated each other. Ever since they were kids, they were always competing and arguing. Haeun was the rebellious and funny girl in school, and Joshua was the quiet and normal guy who played in a band. They had nothing in common, except for Haeun's brother, Soonyoung, who was Joshua's best friend.
Haeun thought Joshua was a boring nerd, who only cared about music and his band. Joshua thought was a wild troublemaker, who only cared about pranks and jokes. They avoided each other as much as possible, but they couldn't escape their mutual presence in Soonyoung's life.
Things got worse when they were assigned to tutor each other for their final exams.
He would like so much his best friend to love him like he does, but his best friend only sees him as his little brother. What's more, he's just gone through a break-up, and it's hard for him to forget the boy he loved so much.
Yet it's at times like these that we realize who we can really count on and, above all, who we can really love.
