Key- A boy with many flaws or so he thinks. Key believes that he is the cause of many of his loved one to be harmed, therefore he decides to shut himself from society. His daily routine consists of going to school, working a part-time job at a Cafe, and taking care of his ill Grandmother. He doesn't have any other relatives that he is aware about, he was told that his parents didn't want him so they gave him to his grandmother and left without a trace. 

Minho- Self-centered, only thinks of himself. Never considers the consequences of hurting others. A typical High school Jock that is your playboy. Rich, Handsome, and simply Lavish. Some would call him. 

When wrong paths are crossed, one tries to fix it and the other can't help but grasp on. In the end he must let go so his loved one isn't hurt..
