Jonghyun was moving back to his old school, his old life. He was overjoyed. Of course, he'd miss his friends back in Seoul, but he would be able to see his best friend Kibum again when he moved back to Daegu. 

But when Jonghyun got there, he found that everything was different, especially Kibum. Gone was the cute little boy he had once been friends with. That Kibum was now replaced with a y, curvy man who called himself Key.
