You like to skate often at Hawkins' local skatepark with your board and even attend Hawkins High.
It was after school and you had skated over to the park to skate for a little while before going home while Billy on the other hand was driving back home with his younger step-sister Max who also skated.
Max really wanted to go to the skatepark and kept nagging Billy to turn around so he could take her there. Usually he'd just kick her out of the car for her to skate home or threaten her but he had recently had a bad fight with his dad and he was desperately wanting to avoid him so he reluctantly turned the car around and started to speed down the road towards the skatepark, acting all annoyed and angry at her but he was secretly at least a little relieved.
They had then arrived and Billy parked the car, getting out and locking it as Max already had skated off. He took out a cigarette from the pack he had stored in his pocket and lit it with his lighter as he followed the path towards the skatepark, taking a seat on a bench as he sat back and watched everyone.
Looking around, he was surprised to see you there. He didn't really know you that much but knew that you were in his year and even saw you a few times but other than that you two never really interacted when he first moved to Hawkins. He didn't want to care but he just couldn't take his eyes off of you. Turns out he had just learnt something about himself. He thought skaters were really hot.
