So it wasn't intentional. It wasn't even expected.

Which makes sense. If he'd been the one in Katsudon's position, last time, nothing in the world or out of it would have induced him to ever come back to this place of his own free will again. Not after --

(I shouldn't have brought us here)

A narrow thread of something unpleasant twists through his chest, pulling and tugging and tightening in increments. If he lets it tighten enough to snap, it'll end with him snapping out something that he won't be able to take back. So he huffs out a short breath, hoping that it'll loosen the tension inside him, and says:

'Well, I still need to eat, so if you're going to stay then sit down.' He picks up the chopsticks again -- grabbing them both with his right hand before he uses his left hand to settle one in the groove between thumb and forefinger, and hold the second one in place so he can find the right position like the demonstration had showed. 'It's weird with you hovering like that.'

It would be a promising start if it wasn't so obvious that his grip is far too tight to make much in the way of progress, at the outset.
