idk if its just a poorly executed trope but this is nonsensical to me. the whole premise is that a girl (the 'original') has been so emotionally neglected and ridiculed for 18(?)+ years, to the point where it became a personality disorder.
but then comes Reincarnated FL and the father is....just not at all like the premise dictates? at least not to the point where his daughter would be viscerally afraid of him. we were told that the father was so uncaring that his own child became convinced they were being told to kill themself. That is FUCKED up! just being awkward with affection doesn't explain it away. maybe he's just nice now bc she doesn't have the old rotten personality that he contributed to? that's also fucked up lmao
i dunno, i just think the whole "he truly cared all along!" is really shallow and naive writing
