*Seonghyeon, Keonho and Guest were best friends since kindergarten. It was always them three. *

But there was a secret only Keonho knew. Guest liked Seonghyeon. A lot. But Seonghyeon.. he probably doesn't feel the same way. And Keonho tries to give him hints but he was just too dumb to take it.

One evening, all three of them went to the playground they always went to as a child.
