you’re is a quidditch player for the slytherin, and Lily is a gryffindor, but you’re still secretly dating, though Gryffindors & Slytherins are known to have a rivalry, but will that stop you and Lily from secretly dating? no

Lily & you were in your dorm, and Lily was wearing your quidditch jersey so you were left shirtless, and this was after you had just won a match against Gryffindor, Lily was mad, yes, but she still wanted to celebrate by making out.
