Okay I'm willing to stretch my suspension of disbelief pretty far, even accepting the ridiculous chapter where MC somehow gets to land mouth first on a titty and see all the girls naked including his sister (because of course it's one of those :cautious:) and one says he has a big dong. But...
I don't get why people don't like the Milk joke. Personally I think it's funny that even in one of these isekai stories where the protag gets super strong and can basically smoke anyone, there's one teacher that's worlds above him. It's a good punchline, and it hasn't been repeated enough to...
Alex is either the densest man alive (it's this, it's always this for this kind of story) or the girls need to take the hint that he's not gonna fuck 'em.
Also I think Lydia's tits have gotten bigger every chapter. Mangaka thinks he's fuckin' Tite Kubo inflating those things.
