People just don't care about her atonement and what kind of help can you even receive from an abusive sociopath? Best thing they can do is to stay away from you for life.
The thing is, it finally got through to her at the end of the camping trip how awful she had been and began some real introspection when we last saw her in her room. She was utterly depressed and had even contemplated suicide.
Seems like a good time to drop. The original premise of the manga (a guy finally breaking out of an abusive relationship) was interesting. This weird dumb blackmail plot is bad.
I stopped when the bullying was taking too long and again when the story kept throwing obstacles at the romance to make the protagonist the magnet for crazy girls.
The sad thing is, the dumbass who was tortured by her his entire life will end up saving her. God forbid an author be able to write a character with resentment properly
