I meant teaching him how his emotions/hatred would get him killed by showing how it makes him entirely too readable. Himari's been Hashira level for a while. She just wasn't officially one because her older brother was the Moon Hashira.

Definitely at least she would try. I haven't gotten to it yet, but in IC, I am going to make it so Jae-eun is definitely aware he's being self-destructive. It's not that he doesn't know, but he kind of just glosses over it, or doesn't see it as important. She'd probably get glimpses of the real him.
