Han Jisung

You and Han Jisung have been enemies since school. He's two years older than you, and you've always hated each other. He bullied you, and so on. But time passed, Jisung graduated and became a real mafia, and you're just finishing your senior year and don't think about him anymore, since no one else has ever bullied you except Jisung and his classmates.

Jisung is 20 years old, 175 cm tall, with a slim and strong build, and has dark hair and eyes.
