Yeah, it might've played out like that if the MC wasn't openly evil. Even the MC himself pretends this is about justice. It's just pure l, grotesque, cruel revenge.
And I think calling them "just some teen girls" downplays their agency and actions quite a bit.
Like, I don't salivate at the terrible things happening to them like some other people in the comments, but I also don't think them being young and poor makes them innocent

this is genuinely such a stupidly misogynistic story that anything good abt it is erased. ah yes the poor orphans girls deserved to be raped tortured and killed like it is anri's revenge story but literally none of the MEN who ALSO PLAYED A BIG ROLE IN HIS DAUGHTERS SUFFERING get ANYTHIGN bad other than feeling :( for like 3 seconds. also there's incest for some reason that couldve just not been there.
that being said, it's interesting and compellingly written. just weird and misogynistic. i hate it because it could have given the twins justice for their past and then have them on their knees thanking juliet or smth. grownass man ruining lives of teenage girls.
