The story envolves around Kwon Tsurashi, Song Eri, Jung Fern and Kwon Momo, four girls in their 2nd and 3rd year of high school.
They've been close as long as they can remember, always doing everything and nothing together, they're pretty much inseparable. Or?

That's were the story starts.

One day, four new students transfer to their school, Lee Taemin, Kim Kibum, Lee Kikwang  and Kwon Jiyong. Of course everyone gets hyped up, the girls included. They all start to get a liking for their new classmates, but it all doesn't seem onesided to their surprise. The guys are starting to get interested a bit... too fast... or are they?


Tsurashi a happy girl who easily get annoyed. She loves dancing and hates school. Her grades but she still keeps up with it due to the support from her friends. She can be really clumsy and kind of an idiot at times, but when she actually uses her brain, you'll be surprised by what she can come up with.


Eri a really happy person, but sometimes really clueless and doesn't quiet understand what exactly is happening around her. She fell head over heels for someone and is hopelessly in love with... a total jerk? She can be really stubborn to get what she wants, but she's sometimes too nice for her own good.


Fern the girl who's always fixated with her grades, studying hard to reach her dreams and "the brain" of the group. Even tho, she's really clumsy and sometimes doesn't even realize the most apparent things.


Momo, Tsurashi's older sister by a year. She always and the others, can have a really y and cocky attitude, but then you get to know her she can be really caring, and let's just say that... she's not always the smartest.


Taemin, the happy, clueless little guy, who loves dancing. He lives together with Key since they were kids. No wonder Taemin calls Key "umma", right? He's really shy around new groups of people, but when he's alone with someone, he's really talkative. This is something someone soon will find out. He seems like a really careful person, always nice and does nothing wrong, but there's another, hidden side of Taemin not many people come to know...


Kibum, or Key, Taemin's "umma". He can be a real diva with a cocky attitude, but once you get to know him he's really kind and thoughtful. Always take care of others + a real fashionista. Just don't piss him off, or hell will break loose, literally. Pissing off Key is like digging your own grave.


Kikwang, a really mature, daring and neat guy.... or not. He seems like the really mature and neat guy and that's what he pretend to be, but around his friends he's a real dork, and stupid. He's really clueless to the point where it's not even funny anymore. He might seem like "the cool guy" that doesn't talk to normal people, but that's only because he's shy. Really shy. But he can be very charming.


Jiyong, or GD (G-Dragon), the b-boying-rap-freak. He loves music and spend a lot of time composing the right music with the right lyrics. He usually acts cold around new people and never show his real love to music. He might look really tough, but deep inside he's just a sensitive, shy, happy little guy stuck up in his own world of music.
