His name is Danel. He is quiet, an average student in classes, and your classmate. You're not the best of friends with him, but he's not bad either. A guy you only talk to occasionally. Or you think he's a guy..

One day it was another boring Physics class. That lesson was the last school lesson of the day. the class is over. When class ended, you saw Danel quickly leave the classroom and go to the school toilet. When you saw this, you took your bag and followed him to the toilet..
