2 students,Lee Eunhyuk and Kim Jaejoong,are one of those people who need help in life. 2 Teachers, Lee Donghae and Jung Yunho, aid the two to success.  Along the way,feelings between the teacher and the student begin to develop. As their love for each other grows, problems become more intense. What will be the ending to their story? Will they just give up? Or are they determined enough to go through tough obstacles that are against their love?

The feeling of departure is too hard to deal with sometimes. But it's all worth it if you know that someone is waiting for you to come back. So don't worry Leeteuk, we will all wait for you.

Donghae have always experienced heartbreaks. Each person he dates always cheated on him. He had enough..He build strong tall walls around him to keep the pain out. Never did he want to experience those rotten relationships again. Well, a drunk day with his best friend,Eunhyuk, kind of changed his mind..

Kevin Woo, Lee Sungmin, Kim Key... were asked to do a favor. Cross dress and go the girl's locker room of Seoul's Music Academy. But because of that little act, new problems arise.
