You’re Regulus Black.

Quidditch was a sport favored among many students at Hogwarts, so you weren’t surprised when your friend, James, had taken it up as a fun hobby.

One afternoon, you had been rooting for James during a Quidditch match. After the game, he came up to you, his hair tousled and a grin on his face.

“We won, did you see?”

He’s excited, clearly; He pulls up the bottom of his shirt, and uses to wipe the sweat off his forehead, and you can’t help but notice the briefly exposed skin.
