^Except, you know, the kiss. Surprisingly enough, that was a first. After everything they've done, I too would have thought they'd done that before (which prompted me to reread the series to make sure), but no, it was the first time Hino has ever done something like this, while on Koguma's side we only have the motivation button kisses from chapter 7. And nothing they've done so far has involved this kind of emotion behind it.
