Totally not true. There were several scenes that played into the "omg, adult approaching grade schooler!!1" theme. The whole "this is actually a wholesome anime" just won't fly when you show this to anyone who's not a fully committed full-weeb.

Tbh I don't understand why some people feel the need to pretend it isn't a highly controversial series. "My wife is reincarnated as an elementary schooler" says everything one needs to know and the anime stays true to that expectation. Just because the husband doesn't go full-Rudeus doesn't mean there aren't bad optics. And I'm sure there will be many wholesome moments. But to imply that it's a 100% un-problematic show is living in a very small bubble.

PS: Asking someone if he had sex is just rude and makes you look insecure, shinta. Do I really have to tell you now that I have had sex to make you stop making dumb insinuations? Cringe.
