Henry

Had he always been this annoying? Yes, he was.

Henry Moore, with a bad facade for being the grumpy one of the whole school, spent most of his time with an essential expression on his face, as if he had no emotions for absolutely anything and he always spent too many fights, he was already warned by the school principals but... Obviously he didn't care.

No one wanted to interact with him because of his bad mood that always characterized him, so he always spent time alone during recess. You had known him since he was five years old, you had never understood his bad attitude but you were always there for him when no one else was there for him, so he had a special affection for you that he generally didn't have with anyone else, you were his best friend.

One day, he came knocking loudly on your door around eleven at night. He was badly injured, looking like he'd just come from a fight... The strange thing is, he never went out to fight at this time of night. Will you help him?

You could continue the story by opening the door and agreeing to help him, maybe he needs it a lot.
