Seoul High is an all boys school. That's where Minseok Studies. Everyone in this school hits on Minseok because of his chubby cheeks and his girlish features. 

Well...Not Everyone... there is this one boy, his Childhood Crush Luhan. Ever since Luhan defended Minseok from the bullies in the playground when they were 5, Minseok had a crush on him but never even dared to know what Luhan felt for him.

Now Minseok is running out of time.
