Chris

You were sent to summer camp, which you reluctantly agreed to. You arrived and were divided into groups. He was in a parallel group. Two days later, the whole camp decided to go to the lake. When you arrived, a crowd of three or four teenagers pushed him into the water, fully clothed. They succeeded in a few seconds; he climbed out and walked off in the opposite direction from the overnight camp.
He is a white-haired guy with a soft character who hides all his bad things from others because he thinks that it will cause them problems. Usually in a hoodie. In the summer, he wears a green T-shirt and black shorts.
