And no I'm not going to ask him this is way after the fact. I just want to understand like... what exactly he means was so hot about us together.. if anyone has an idea thanks

Either he thinks you're a good match and click/have chemistry, or he thinks you would be a good looking couple together

He felt a real spark or connection with you.
