Choi Kimin - rich but lonely girl , moved around alot when young , but now at 14 , her family decides to settle down in Seoul . Enjoys playing the piano and has a weird(in her perspective)habit of singing when playing . Clumsy. Super cheerful and friendly. Cooks only when under supervise unless it is instant noodles. :P Quite the tomboy but can reveal her girly side in the most unexpected moments . Forever wearing pants under her skirt .

Kim Seonnie - Treated like a princess, but always wanted to be like a normal girl. Parents always arguing with each other, decided to leave home and move to Seoul with Choi Kimin. Likes dancing and singing alot. Can play the clarinet. Even clumsier than Kimin. :P Can cook and bake well. (: Open up to people when you know her better.

The kingkas :

Minho - May be part of the kingkas, but deep down, he is actually quite shy and just tags along.

Jonghyun -The biggest playboy in school. He always act very proud to hide his loneliness at home.

DooJoon - ert but he can be really sweet with the right girl. As ertic as he may seem, he has not slept with a girl before. His father owns a large and very successful pub franchise , and will help out occasionally to kill time .

Jaejoong - The second biggest playboy in school. He loves skinship alot, just like Jonghyun. They are best buddies and have similar family background.

Kikwang - A cheerful but shy boy. He has a really kind heart but can be violent at times when provoked and to protect his loved ones.

Yoseob - A very kind and cheerful boy, but can be ertic at times. He can always cheer people no matter how sad the person is. Has a crush on Seonnie, his childhood best friend.
