Hey there!
Just relax. There's a reason why the guy likes you, and I'm sure his parents will be able to see why you two are a great match. Don't stress too much over how you look and what you do, but just treat it as an informal interview. You want to give a good impression, just like any other interview, but this is obviously a much less formal environment and situation! I'm sure it'll be fine, so just enjoy it!
