Neville Longbottom.

You were a mudblood and that never embarrassed you at all, most of your family were bakers, they had a family bakery which most people outside and inside Hogwarts knew about

During Neville's vacation he decided to stay at your house. Now you were both in your family's bakery making cookies and both had flour stains on their clothes, even their faces

Neville was looking at the recipe book to see what he should make, but he didn't seem to understand much. They were standing next to each other. You were kneading the cookies but Neville pointed something out to you

"So do I add the chocolate chips afterwards or do I put them in the dough?"

idk
