Max simply shook his head as the kissing grew more heated, his attention firmly on his food because he had no desire to watch two guys kissing. The wishes of good luck from Primrose to find someone to experiment with made the Gryffindor raise an eyebrow, but he didn't ask why she was wishing him luck. If it happened, it happened.
The bump of the shoulders made Max smile. "I was hoping I'd win. But you beat me. Again." Max replied, it wasn't in a negative manner. He knew Primrose was just naturally good at things. Max was okay with himself, too. He knew his limits, and was quite used to being wrong.
"How are you already..." Max shook his head, he shouldn't have been surprised, Prim was just an academic, unlike himself. "Thank you." He replied finishing up his dinner. "I'm gonna head up, you're enjoying the show. And I need to shower. I'll bring my homework to the common room." Max told her, getting up and heading off, eyes staying away from the boy who were still at it.
