I dont get it. MC was pretty much used by his wife and daughter to the death. But he blames himself. He basically a dream man for a lot of modern women. Provides and wants nothing in return, takes blame for not providing more, ignores wifes cheating and daughters disrespect . And in isekai world he decided to be even more usefull? Wut? I hardly ever saw a character in more desperate need of some balls. At this point asshole hero is closer to be a normal human being.
