Jesssica Jung has been struggling with self-esteem for all of her life. She doesn’t really have any confidence in anything, except studying and painting. Perhaps it’s all started when her Mother passed away when she was still a kid. On top of that, her stepbrother keeps bullying her –unintentionally- by teasing her that she is ugly, flat-chested, short, and unattractive. That’s why she keeps thinking that she doesn’t deserve Lu Han, The Most Wanted Male in Seoul High School, to be her boyfriend. Lu Han himself, doesn’t make anything better for her. He is so unromantic, so uncaring, so clueless, and so casually cruel.
