Lee Eunhyuk is used to being in charge. No one challenges him and gets away with it. His past is what made him the way he is today. He will do anything needed to be in control. He's a fighter, and is the last person you want to mess with. He likes to think of himself as your worst nightmare, and some of his victims would argue saying that that is an understatment. He's biual, but leans more towards men. Everyone knows this, and no one is stupid enough to make a statement about it.

Lee Donghae is an exchange student from china. He is forced to live with Eunhyuk. They clash immediately and are constantly at each other's throats. What's going to happen between the two of them? He's a kind person, and an all around nice guy. People tend to flock towards him for his charm. He just came to terms with his uality right before leaving China, and finally isn't afraid to admit that he's gay and proud.
