Ok I've tried to get into this manga several times, but I have a MAJOR problem with its writing: The story has no respect for its characters. Every character not only has some major flaw to their character that makes them unlikeable, but even their actions feel forced. I understand that problems can also arise when characters have no flaws, but for a reader to be invested, there needs to be likable characters. Having every man be either evil, insignificant, or a pervert while every woman flashes their underwear or cleavage every chapter makes me ask myself "why am I reading this?" over and over. Not to mention, the main character ALMOST has a good backstory of "NEET that wants a do-over", but any development is done with his actions (leaving the house, getting stronger, etc.) rather than having his personality change at all. I've read stories that have a very unlikeable main character (Overgeared comes to mind) but all of them are engaging because the reader wants to see how the plot will interact with said character and how they will develop.
Sorry if I seem overly negative, but I just had to get that out. I'm sure that if you can get past the character flaws or even empathize with the characters, this is an enjoyable story. I just don't see how it's so highly rated.
