I don't have too many problems aside from the dad and Rudeus with his women. When his dad slept with the maid I thought it was resolved pretty ok and I could live with it, but the fact that he still slept with other women WHILE his wife was away was just a bruh moment. Rudeus I actually like because hes a garbage human but learns to grow. Also, I see a lot of new readers from the new airing anime episode right now and everyone just seems to drop it after a few chapters but the characters grow and become better people, this isn't just a cheesy isekai where the MC is perfect and respects all women, no, he's a shut-in otaku who's in reality an actual piece of shit but we can see SLOWLY that he's growing. The main problem I have with this is that (spoilers) He ends up with multiple women. I'm not that biggest hater of having all the women have a happy ending but come on. Just pick 1 person and 1 person alone.
