Charecter Descrition: 

Jessica ( Sica ) : Secretly she could have been Onew's girl version: Pretty random, forgetful goofy and loved to have tons of fun, be care free. But life happened and she was bullied a lot in school and though she was the most sharpest in the school she would still get bullied, hence she adopted the "Ice princess" attitude. Well she hated it as it was not who she is, but it helped her a lot. Now no one dared mess with her. She was fearless, calm always distant and cold. Boys loved the mystery,  girls scared and jealous. Jessica had just 2 friends. They were the only thing apart from her favorite classes she looked forward to in school. And they made her life livable. 

Jong Hyun: Things always go his way. The hottest person to walk the school with  his equally hot friends he was the man on the campus.

Getting girls was a piece of cake. But he has a secret: The lady killer becomes nervous as hell and shaky when he sees a girl he likes.
