The child of the woman you loved, yet you neglected her to the point she died of a fever.... another scumbag dad. It's too late to repent since technically his daughter already died.
Holy crap! She basically described how FLs in abusive/neglectful households react at the end when they get isekai'd or time travel back to the past. They either act so different that things change, or they just leave, which also causes a change. It's generally the former, but the latter happens as well.
But I prefer that she didn't even give the chance for things to change before she just ditched the house.
