Living a life that you were never use to, becoming friends with guys that people around you look down upon. Falling in love with a person that can make dozens of people wince in pain, but can make you smile and feel like a princess. Although you didn't know that all of this would be happening to you. That seeing your dad would be a scarce thing, running and hiding from loansharks would be a daily thing, and that falling in and out of love would be a common thing.

Song Eunji 

Used to living the luxerious life, but was never one of those girls to think that she was better than others. Her dad used to own one of the biggest companies in Korea until he started losing money, and building up debt from loansharks. Her mom passed away from an car accident when she was 12 and her dad is the only one she ever felt comfort in. She's left to live by herself, while her father goes into hiding and she keeps the secret from her classmates at school. Not loud-spoken but not timid either. She has long brown hair, and brown eyes, with pretty features. Myungsoo's soon-to-be neighbor.

Kim Myungsoo

Lives the common life, just enough to get by. His friends mean everything to him, and he could never betray them or leave them. If one of them is ever in trouble, he'll always be the one that will be there no matter what. With stares so cold, that even criminals would flee. He loves music just about as much as he hates school. Plays the guiter in his band. Although the band is nameless, since they're just playing for the fun of it. 

Lee Byunghun

One of Myungsoo's bestfriends, a troublemaker, but then again, all four of them are trouble makers. Caring, funny, and good-looking. He starts falling for Eunji as he develops a friendship with her. He plays the bass.

Jung Daehyun

Myungsoo's bestfriend also. A food-lover, and face stuffer. Friendly, and is a busan boy. The main vocalist of the band and falls in love with one of Eunji's bestfriends.

Yang Yoseob

Bestfriend #4. Soft-hearted, the cute one, and a child at heart. Although he's probably the best fighter next to Byunghun and Myungsoo. Plays the drums and sings. He also starts going head over heels for one of Eunji's bffs.

Anh Nana

One out of the two of Eunji's bestfriends. Super funny, and definitely has a backbone. Not afraid of telling people off, and is totally in touch with her ghetto side. Really pretty.

Lee Ara

The other half of Eunji's friend-triangle. The sweetheart of them all, kind and funny. She's the type that no one has anything against, because no one could possibly hate her. Really pretty.

"As the two of us face each other on these rooftops, we both wonder how we're gonna get down."
