Key has always been the quiet kid at school. He didn't talk to a lot of people after an incident that happened awhile before his sophomore year. He used to be quite popular, actually. After that incident, everyone just left. Ever since then, he's been alone with no one to talk to and no one cares. 

He's happy with his life. He's used to being alone and not talking. What happens when Jonghyun, the new kid, shows up and suddenly gets interested in him? Will Key be able to open up? Will Jonghyun be able to break Key out of his little shell?
