Taemin and Krystal were friends since trainee, and of course they had had crush for each other since then. They used to be inseperatable and very, very close until one day, all in sudden, they didn't greet each other anymore. For no reason. And that was how the two youngests then became so far away from each other.

One day, to celebrate Jonghyun and Luna's relationship, f(x) was invited to SHINee's party. It then became another world's hell for Taemin and Krystal--would they really meet and make up everything, or meet and act like nothing happened?
