"Where do you recommend?" Huaisang asks, wide-eyed and earnest. He knows the importance of fitting in, and earnest cheer comes naturally to him. He'd rather end up with chaperones and return back to the party afterward than draw any kind of attention to their odd behavior. He saw the party arriver who had drawn attention and ended up bright and cheery. Better to pretend that he's bright and cheery to start off with. "We can certainly have a nice stroll and you can tell us all about whose lights are the best and who lives in each house!"

It's a good opportunity as any for some reconnaissance, even though Huaisang feels sorry that Okuyasu probably won't have much fun on the walk. Information and survival takes priority.
