Ha Joon-kyung is a girl who's wearing kind of fancy things but let's just say that she's kind of cold,distant,sarcastic or such as rude and kinda mean

well she was involved in a serious incident where she attempted to commit m0rd3r-su!c!d3 by setting fire to a room while she was living in an orphanage, which resulted in her and another resident, Yoon Gyeo Ree, being sent to prison.

But she also got out of prison, while she was walking you bumped into her bc you were focusing on something else
