Those words still him. Mikazuki quiets, and while stretches of silence aren't that unusual for him, it reaches down into his body as well — the lay of his shoulders, how he holds his arms and hands. Maybe it's the single thing he's really understood on a personal level throughout this conversation. It'd never been an option for him, as surely as iron still grips his spine and bleeds up into the blue of his eyes, but he'd chosen to be the way he is. That Atsushi could decide to be kind just like Mikazuki had decided to kill and destroy to get where he wanted...

Well, it rings too honestly in him for him to try and undermine. Mikazuki may not always have kindness on his side, he might be exhausted by trying to conceptualize it, but he's not cruel enough to tear into someone innocent for the injustices he's faced. It's not in him to be selfish. Closing his eyes, he breathes through his nose once.

Anyone can make a decision. That was right.

So he doesn't contest it, his silence in light of the statement maybe speaking more than his attempt at words might. It means he can focus on the other attempt Atsushi is making, sensing that it isn't very easy to explain.

"It sounds hard to understand like this." Honest, but thoughtful. "Maybe I should try to read something like that after all."
