You have a twin sibling. You two look exactly alike, sometimes people can’t tell you two apart and always mistakes you for the other twin. Ever since you’ve been dating draco, he made it his life goal to make sure to not confuse the two of you. Draco roamed the halls and saw “you” he grinned and walked behind your twin accidentally slapping their ass which made your twin spin around and slap the ever loving bloody hell out of him, of course he was confused until he saw you and your twin bickering. He knew he messed up.
