How long is forever? Kim Ryeowook has been in a rough patch ever since his splitting from his boyfriend of a year+, who coincidentally enough, is also living on his floor.. as a member of his band. Already in a bad situation, he unknowingly (though not for long) finds himself an admirer, one of whom is extremely persistent in getting what he wants.

That-

Includes a transfer to the other side of the world, and the small singer himself.

    . :  Midst the confusion that comes with romance, at home, (cross) members Cho Kyuhyun and Lee Sungmin find themselves in a bind of their own.

Situations change, problems arise, doubts lift, and Ryeowook is forced to choose between a past that he can't seem to let go, and a new start in his romantic life. Is it really worth it to wait for the impossible to happen with his quiet ex?
