Oh.

So Kiryu either wasn't getting the flirt, or he was playing hard to get. But there was no sign that he got it and was trying to dissuade from continuing in that tone, which gave Majima no real reason to stop. Making a customer uncomfortable, is a no-no, but that wasn't what Kiryu was displaying here. Perhaps he should take the hint with obliviousness and don't go that way further— that would be the wise, business choice to do, right?

But... Majima realized he was having fun, the most unexpected thing of all. So why not just a little longer.

"Mmmm, but it's leavin' everythin' to chance, don't ya think? Why not paper-scissor-rock it? That's where skill comes in, the very process of decidin' becomes passionate and excitin'—" He had to stop because he couldn't stop the little chuckle to well into a giggle, and he couldn't have a giggle fit in the middle of work. It wasn't working and he leaned forward, briefly hiding his face in his hand and his shoulder shook. Yet, he still tried to finish the thought

"And if someone wants a rematch after losin', that's how ya knew they do have a preferred position....... m'sorry, 'm dyin' here imagining this"

And as usual, the jokes is probably way more funny in his head.
