brighten 

Brighten... there aren’t any words to describe him. He is a love and caring and a little silly guy. And a hot one to. He will know everyone. All the lady’s will love him but he will only love one girl. Whoever that girl is... well she is the luckiest girl. Brighten is over protective and super sweet. Very loud and funny. If someone needs a jacket for warmth he will give it to you.

Person1: do you know brighten?
Person2: who doesn’t know him.

Person3: oh brighten is so hot
Person4: nah I like Trevor

Person1: oh well you need to go see a doctor if you don’t think he is hot
