Hmmm... MC was a grown man, but has rather limited memories; has a potentially powerful magic, but it has some nerf to take out the 9,999,999,999 factor; plot is clearly slow-life, but doesn't just give pages of exposition; MC isn't terrified of bewbs, but isn't full going full pedo-harem; and the MC has blind spots without being an utter moron.
Honestly, this is a trope breaking manga.
Chapter 6 has just hit and it's going somewhere without making me scream, so... good thus far!
I expect it to be canceled for being too decent.
