I thought this would be the typical dense manga protagonist.
Turns out he's not too dense (not shonen protagonist level at least) but he's afraid of dating the much younger women near-literally throwing themselves at him.
Overall, not a great story, but at little original.
As a sidenote... not isekai. The tag is wrong despite a few strange anachronisms.
This looks like a fantasy world, but they're talking about TV and movies?
