It started off good but then it started getting weird, he was about 60years old when he died yet when he goes back in time he is 9 (8 but about to be 9 that year) and there are already girls flocking to him which is just weird since they are all UNDERAGE and yes I get that he is physically a child but the author could have easily added the harem after he gets older and the women are at least 18, second part it doesn't have a Harem tag but this is straight up Harem. I'm not a fan of harem or reverse harem so I was disappointed when I read it and started seeing a pattern of underage girls bing constantly introduced and immidiately wanting him.
I wanted a story of revenge and action not a harem fest where the MC isn't thinking ahead but instead just getting lucky with his dad supporting him. I wouldn't even say he was OP from the start after he returned back in time, it's more like "Oh I am too weak" right before he passes out after only using mana for two punches, then out of nowhere BOOM I am no level 1 then BOOM "HE IS FIGHTING A RANK B AND PUSHING HIM BACK?" without fainting. It just kills the progress and it's sloppy writing.
