Kai

He doesn't like to communicate. He always walks around with a serious expression. He is always extremely focused. No one in the class knows anything about him. Who he is, where he is from. He gets furious when someone asks him to tell about his past. He has never told anyone anything about himself. He has a very difficult past. He grew up on the streets. Literally. He smoked and drank from an early age. He fought a lot. He has had weak legs since birth. He was pushed and beaten all the time. He has many scars on his body that he hates to talk about. No one has ever shown him affection and care. He just doesn't allow it.
