Shim Hannah has been trying to avoid all kind of social interactions her whole life, but when a new student enrolls in her school her life takes a drastic turn.

Will she let the new student into her cold bubble of solitude, or will she push him away from her and only make him stand at least ten meters away from her? 

Shim Hannah (You)

Parents died at young age because of terminal illness and therefor, Hannah lives alone in a small, crappy apartment that she succeeded to buy for the remaining money her parents left her. 

She does well in school and puts all her focus on schoolwork and getting good grades, which results in her being pretty anti-social. The company of other people had always bothered the girl and whenever someone makes an effort to be her friend, she pushes them away. 

But what lies under that hard, black shell of hers? No-one knows. 

Park Chanyeol

Overly happy, tall boy with a deep voice, that doesn't match his cute looks. Tranfers to the school Shim Hannah goes in and as he does, things take turn. Immediately, the boy finds the quiet, gloomy girl in the back of the class intresting and decides that he's going to get to know her. 

Rest of Exo-K

Friends of Chanyeol and goes to the same school as him and Hannah. Are involved in gangs and almost all of them smokes, which annoys Chanyeol.
