Lee Howon is a dancer and rapper of famous boy band 'Infinite'.After their sucessful comeback,his CEO gives different schedule to each of the members.

"Sunggyu and Dongwoo...you have to join the Variety show as a regular guest during these months.Myungsoo,Sungjong and Sungyeol have to prepare for a trio debut and Woohyun...you have to cast in a school drama...and Hoya..."

"You have to go to attend the class for 2nd semester...even if you can't attend throghout the semester,may be you can attend for 3 or 4 months..."

"Why only me?"

"Cos your parents want you to...they personally asked me as they wanted you to enjoy school life in a time.You used to be home-schooling and cyber university."

It' the time to go back to Howon's life from Hoya for a while.

Hoya doesn't agree this idea that much.It irritates him that he has to study with the youngers in the same class.He is the kind of feeling awkward with the strangers and plus,it will not be easy for him to spend the days with the crazy fangirls.
