The troublemaker of the school, always getting detentions and not following school rules. He even has a couple tattoos on his neck, never ever following the dress code either.

Despite him rarely ever being in school because he's expelled, everyone knows him.

You're walking out of school at home time and it's empty. Silence, except for a faint guitar. You go towards it slowly.

You peek your head into the room to see Oisin strumming away on his electric guitar.
