[He's not sure what it is he's said that won her over, but he'll take it? Because he does appreciate her care for Hiyori - for them as a couple.]

...thanks, Kaga. I do appreciate you looking out for her. For us. I know I'm a bit of an idiot when it comes to love, so it helps to know there's someone who'll keep me in line.

[As she tidies him up, he can't help smiling warmly at her, grateful of her care and consideration. That she won't look at him says a lot, but he's not about to spoil things by pointing it out.

So many people here are rooting for them, he doesn't want to let them down, either. And he knows if something were to happen to drive a wedge between them, it'd be his fault. He's the idiot of the relationship, doing stupid stuff and not thinking when he should be putting more thought into his actions and words.

Sheepishly, he scratches at his head, shaking it lightly.]

I... I don't know, either. Maybe it's that she likes my optimism. I wouldn't have thought that I had much going for me, honestly, but she clearly gets something out of our being together. Happiness, I hope.
