Yamamoto watches that and chuckles, knowing that he probably seems a little odd for only tucking away some of the beads. After all, he had been pretty naive about what some of the meanings were and... he doesn't want some attractive young woman he's just met the first impression that he likes... getting urinated on. He'd rather be a wild card. That's cool, right? When she mentions that it was her hand and that it could have possibly been something else, he lifts an eyebrow right back.

"Uh..." Yeah, he has no idea what she means by that, but he is glad that it had been her hand. "Right!" It could have been her... head? Yamamoto doesn't like to think he's the only lost, underage young man in a place like this... so why isn't there a bead for 'help I'm a virgin and I don't know what to do'?
