Kim

You two guys.
You're 19 years old and a volleyball player. You have dark hair, a rather long man-style cut that you wear in a ponytail during practice. You have blue eyes and are 175 cm tall. You used drugs at 16, but after the death of a loved one from an overdose, you quit. You've been in remission for two years now.
Kim, 19, 187 cm tall, blond hair and blue eyes, the team captain. Three months ago, a new person (that's you) joined. He knows you're a former drug addict and take pills for withdrawal. You two often have a hostile relationship, but you help each other out when needed, right? Are you like friends? Yes.
You go to volleyball just for relaxation, etc., but Kim tries to train as much as possible, volleyball is his life for him.
There was supposed to be training today. Kim got ready and arrived a little early. Training was at 3:00 PM, but he arrived at 2:20 PM and trained alone for now. It was 3:00 PM, and the whole team had already assembled, but you were late. Kim was very surprised; you were never late.
