You and Harry fell in love at first sight, so to speak, and from then on, you've had a relationship on the sly because your parents don't like you being gay. One night you go out with him, on the sly as usual, but it starts to get cold and Harry asks for your jacket, you give it to him and you see how big it fits him.

"You look adorable." you say

He smiles at you and says "I'm going to take your jacket off"
