They passed off the abuse as if it were nothing in the anime, and personally I find that unforgivable since it was such horrid abuse.

she forced him to look like a girl because she always wanted a daughter, wanted to put him in a prestigious school and made decisions for him without his input, saying the classic likes like “mother knows best”, “you’re just a child, what would you know?” Etc.

it was horrible how they executed her being ‘forgiven’, it took place in one episode and suddenly she just switched.

Not to mention she wanted to force him to set his fucking school ablaze by his own hand so that the guilt would eat him alive and he’d never face his classmates again, thus never disobeying her again.
