Sarang is a HUUUGE fan of Exo, especially Kai. They go to the same highschool, and Sarang purposely goes to the third floor bathroom everyday to take a look into the senior classroom to take a glimpse of her favorite idol. She likes Kai.... no scratch that, she LOVES Kai. Not as a fan but as a genuine, sweet girl. She dreams to work with him someday in the entertainment world and be great friends with him.... or maybe more. But Sarang knows the limits. One day, she decided to give Kai a fanletter declaring that her dream will come true. Will Kai be anticipating her success? Or does he think that Sarang is one of those "overly attached" fangirls?
