Ron had no idea the things going through Hermione's head at the moment but that really wasn't any different to any other time. She could be very hard to read sometimes but really, he wouldn't have it any other way. His mind was far too preoccupied with thinking of a way to bring up and ask the moving in together thing at the moment.
"Yeah, Harry and I try to pair up when we can." He shrugged slightly. Moving forward slightly so they were standing closer, he grinned at her. "I'll have to try a bath next time too then." He said, speaking softer since they were standing closer.
And, with the way they were standing now, he couldn't resist stealing another snog so, reaching up to take her face in his hands, he leaned down and kissed her again, gently, but still lovingly.
