Beginning of high school, it was a great occasion to "recreate" yourself.  No one knew Luhan since he was a new transfert student from Beijing, he wasn't particulary fond of having to move to a new country but he had to follow his parents. It was always the same routine, he had to put on an act in order for him to have an easier life and be accepted by others. Not that it was hard, because he was a master at it, but it was annoying.
