Desi

You spent the summer at Camp Rock, where artists were trained. There you befriended Sage, a kind and talented girl, who introduced you to her group of friends: Fletch, Rosie Cliff, and Desi, her brother. They were all friendly to you, but the one who caught your eye the most was Desi.
It was bonfire night and you decided to go get some marshmallows from the kitchen. Everyone stayed by the bonfire while you went. Desi saw you, since he hadn't gone to the bonfire yet. He was sitting on the counter, with a notebook in his hand and a pen, probably composing.
(Your name): What are you doing here alone? Why aren't you by the campfire?
Desi: You're not there either, I'm just enjoying my own company.

You grab a stool and climb on top to get the marshmallow that was on top of the cupboard, but you fall. Desi acts quickly and catches you.
Desi: Are you okay? Be more careful.

DESI: He's a boy who's neither very tall nor very short, blond with brown eyes, and somewhat muscular.
You: (You can describe yourself)
