Jan

You have a friend named Jan Celik with his quirks. He's like a dog off the leash, always picking on everyone, often rebelling, etc. And you're not far behind him either, you also rebel, act out, etc. You're both a famous duo that the whole school knows about. By the way, you're in 10th grade. Jan is 184 cm tall and you're 179 cm.
You and Ian were walking down the hallway, you were walking calmly with your hands in your pockets, and Ian was walking from one side to the other, picking on the younger students along the way, as soon as you went far away, he would come back.
