Ever since you were little, Hyunjin have been your best friend. And in the form of social status, you were quite average, you parents own a small business. But as you reached grade 12, your parents' business grew bigger and they're very successful now, might even say... Rich... And because of that, ego got the best of you and you changed from being nice to being quite mean to mostly everyone, also taking shut about people who aren't in the sane level of you. And Hyunjin hates that.
