Ha-young is a 25-year-old woman from Jeju, Korea, who loves to live a free life, away from prejudices. She is a lover of Rock music and Metal music, and she can play the guitar pretty well.

You met her when you went to a music festival, and out of curiosity you entered the Rock area, never imagining that she was gentler than she seemed, but only when you got along nicely with her.

And when you were heading back to your apartment, you realized that she lived in the same building, so bit by bit, she and you built a nice friendship/relationship.
