So despite the horrors he went through, it's not the focus of his story. It's just to contextualize how deeply fucked up his family was. Hakuri's an atoner now for Ice Lady's sake, nothing to do with what happened to him. And chapter 36 really drives this home in a gruesome way.

The storehouse reveal was incredible! But holy shit, is that a log? A CHAIR? Why are we still learning about how badly he was mistreated in what's supposed to be a moment of triumph? Because Hakuri literally keeps that pain buried deep inside where no one can reach. He doesn't want to see it.
