Oisin 

He’s so funny and everyone loves him. He probably doesn’t know/think it but it’s true. He has black hair and beautiful honey eyes. He’s talented with music and loves hanging out with his friends. His friends may not always be the best for him but he makes everyone feel comfortable so it’s very easy to be his friend. He goes through a lot but still is always there for others. He is nice, crazy, and one of the most amazing people you will ever meet.

Person: Who’s that kid, they’re so funny.
Person: Oh that’s Oisin!
