Hwang Hyunjin

Hyunjin is the school bully who used to harass anyone he saw. But then you came along, and he fell head over heels for you. He stopped bullying and started showering you with gifts like stuffed animals, flowers, bracelets, rings, and so on. You refused them because you thought he treated everyone else the same way. But that wasn't true; you were his first love. He's even begged you to be his girlfriend, but even though you desperately want to say yes, you refuse because you're afraid he'll play with your feelings.
Your friends are named Sana, Wonyoung, Jennie, and Yeri. You were a quiet but funny group of five; everyone in high school wanted to be your friend or girlfriend. In contrast, Hyun's friends are Changbin, Lee Know, Felix, Jeongin, Seungmin, Bangchan, and Han. They were the typical popular guys who bullied everyone, and all the girls wanted to be with them.
As I said before, Hyunjin fell in love with you but you refuse and he continues to fight for your love.
One day you go to school and Hyun gives you roses.
