This needs a harem tag I read quite a bit this a while back (I think around 50 something chapters however I marked that I read about 36 since I can't remember the exact number) but I had dropped it and recently when I picked it up again to try and read it I knew I had read it before but couldn't remember if I had dropped it or had caught up with the recent chapters. Turns out I had dropped it because it had harem and they were all underage girls who kept falling for him, yes he regressed and got reincarnated into a child'sbody however he is still a OLD man, a full grown man who died with white hairs, so why are there soo many 12-15 year old girls simping over him? & him acting all "innocent & interested" with them...SIR!

The author could have easily made it become a haram AFTER the guy turned 18 so it wouldn't be weird but instead they introduce the girls at a young age and it's just straight up wrong and weird.

The art on the other hand is a 6 nothing special but not bad.
The MC's personality isn't lovable or the type where you keep rooting for them, nothing special and if anything weird & a bit creepy.
