Yunho moves to Seoul and has a very difficult start there. His family is hit hard by the financial crisis, so he has to work, his acceptance into SM Entertainment is said to be a mistake, and he has a lot of problems finding friends. One night, it all gets too much for him and he just wants to talk to someone—but to whom? He can't worry his parents, nor his uncle whom he lives with, nor his sister. He also doesn't want to bother his friends from Gwangju because he knows they wouldn't understand. Plus, it's deep in the night already anyways.

But what about that phone number on the bus seat in front of him? Would it be too crazy to call it?
