[ The pointing with the chopsticks doesn't even register as rude in his mind. Direct is fine. Fuuta has more pressing matters to think about address, anyway.

It's not that Rin's explanation is wrong, as is evident from the way Fuuta clams up for a second. But he can't just accept what she's saying either, judging by the way his face scrunches up in grim consideration, and he earns some time by shoving a piping-hot piece of meat in his mouth -- huffing his way through the hot morsel, tongue singed, swallowing -- before mumbling: ]

It's not like I think you owing me is bad, or anything. Debts and whatever -- I get it. [ A pause before he continues even more reluctantly: ] S'just. You better get that it's not something I did on purpose. It's not like I'm doing anything just to get stuff out of you. I'm not that kind of scumbag.

[ Even after everything, he can't let go of that insistence. Wanting to be accepted as a good person. So long as he didn't orchestrate this situation on purpose, and made it clear that he's not squeezing benefits out of Rin, he hasn't done anything bad, right. Right? ]
