Choi Jun Ri is a normal high school student. Her parents are business man and woman. She has an older twin brother, Choi Jun Hong, who irritates the hell out of her but still, they get along and they somewhat have the same characteristics. Jun Ri of course has a bestfriend named Choi Sulli who is studying in Genie High school which will soon be Jun Ri's school too. Jun Ri and her brother often transfer schools because of their parents' work. But this year, they will settle in Seoul and probably finish their studies there.

Zhang Yixing or better known as, Lay, on the other hand is currently on his senior year in Genie High and has debuted as a member of exo early this year. He's the sunbae of Jun Ri who's currently a trainee in SM ent. after being cast when they were on a fieldtrip.

Genie High is famous for the good looks of its students and some, for their brains. Genie High contains many artists because only the "elites" and the brainies can enter this school.

*Note : I've reduced the of Lay and Zelo in the story :)
