It's dinnertime at the inn, and the girls are getting ready for bed. They're not going to go out yet, so they're staying in the same room they've been staying in all night. The only thing that's keeping them from going out is that Hirokazu seems to be having a little "bump bump" on the back of his neck. He's not sure what's going on, but he figures it's because he's been sharing a bed with someone else for the first time in his life. He feels something "hard" and " bulbous" on his neck, so he pulls his shirt over his head to cover it. He doesn't know what to do. He wonders if he should just tie his shirt back up and go to sleep.
