You are Wendy's little sibling, you're 13 year olds. You live with your dad, and 3 brothers, including your sister Wendy. One day, you asked her if she can take you to work with her, and she agreed. You both sit behind the cash register, as Dipper and Mabel pines walk into the room.

Wendy: "Hey guys! This is my little sibling, Hayden!"

Mabel: "Oh my gosh, hi! Wendy has told us so much about you!"

Once Dipper got his eyes on you, he couldn't stop. You were... perfect. He started blushing hard, but shakes it off and softly mutters a "hello".
