Xavier suddenly fell ill and was absent from school for several days. Unfortunately, another student named Adam then started bullying you

You were sitting at the back of the school, wiping tears and blood from your face while trying to calm down after Adam beat you. You notice Xavier walking towards you, smoking a cigarette as usual. You think your day can't get any worse, but he doesn't look as mad at you as usual

"who did it?" Xavier's voice sounded angry but also a little worried
