Keisuke's journey in that other world, it's much more interesting than the dumb fathercon girls. Sure, it's been done before, but a story about being dehumanized and rediscovering humanity through another only to sacrifice it all in the end sounds like a far better read. I mean, 5 years into the poor guys life in that isekai, he gets his head chopped off while he had regen magic cast on him that caused him to regrow his head from the torso. The first thing he sees after the regen? His own head looking straight at him in the eyes right before it died. That's some brutal stuff.
