[hearing that— even though he had been trying to keep himself from slipping back into that strange place, hearing that gets under his skin like a tanning knife. she had been nothing but kind to him so far, and he doesn't know her well enough to believe that she might act any different around anyone else, so he can only interpret this in one way:

a kind person has been taught to believe that they aren't kind by a group of people that show true unkindness. he pulls his lower lip in with his teeth briefly, one finger gently running around the rim of his tea cup.]

...It doesn't seem to me like a lack of forgiveness in this case means that you aren't kind. Not wanting to give people like that what they want... That doesn't seem like anything unkind, either. It's only natural, isn't it? Not wanting to forgive those who force you into a corner? Not wanting to cave to cruel demands? Looking for a way out? [the more he talks, the softer his voice becomes, but it's a strange sort of softness - hollow and increasingly brittle.] So to say "that isn't kind", and to think that you come here out of spite... It isn't a good way of looking at things, is it? Because you aren't the one at fault here. Don't you think that you should be looking at them rather than at yourself in this situation? You're only doing what you can do, right? They were the ones who created the action that has brought about this reaction. It isn't kindness or unkindness; it's just what follows naturally. This is what they get.

[while he had been looking at his tea, his gaze rises at that, and his eyes lock onto Chizuru's with a bizarre intensity.]

And I think that those sort of people deserve what they get. Don't you?
