Ah, so that was the issue. Belle hadn't thought about the fact that the way she was talking made it look like they jumped into bed with each other almost as soon as they met. "Oh, don't take it the wrong way! It's not like we just jumped on each other. It's hard to explain! I don't think even you expected for things to progress so fast! It just happened..." Oh dear, she really wasn't explaining properly.
Belle softened as he asked that question. It should have been no surprise. Even her grown up Nox seemed worried about what his father thought. "I can't even begin to imagine what there is to not be proud of. Yes, I think he's proud of you, even if you followed a slightly different route to the one first expected of you. I didn't see any signs of disappointment in him when he came to see his son get married."
