Generic isekai fantasy world with no worldbuilding to speak of, loli bride, only overarching plot is that this guy is bad at his day job and his travels to a fantasy world are helping him... fill out sales reports more efficiently?
Most isekai trash feels like it's wish fulfillment for lonely high school boys which makes sense as a target demo. This one feels like it's wish fulfillment for 30-50 year old office workers who would marry a child in a world where that was socially acceptable and can't relate to any positive traits other than owning a car.
I won't argue against it being trash or dumb, as future developments will determine that for certain.
I think this work has a decent amount of potential, gets points for at least being different from the norm at least on the surface.
As far as wish fulfillment: He's a Neoptism hire that gets paid to do nothing and he's MISERABLE about it.
He goes to work, shuns all social interaction, and watches youtube videos all day on the clock - and when he's actually assigned work he's gotten so spiteful that he doesn't even try anymore, misses deadlines, makes errors, and costs the company more money on top of wasted time and a loss of reputation with their customers/partners.
Dude is living the dream, but they hinted at firing him so...
This story is about him learning to be somewhat content with what he has + finding things that fulfill him IN THE REAL WORLD, broadening his horizons, being responsible, mingling with people (in the real world, not just magic happy fantasy land) instead of wallowing in his own pit of emptiness, and having a more full life experience- instead of being hit by a truck, getting video game cheats, and slaying suspiciously-aged girl's undergarments.
Honestly as the target market of 'middle aged salary men that have given up on everything', I'd settle just for the nepotism job where they pay me to do nothing but never fire me because they would hate to shame their gratitude towards my father's loyal service.
You're never lonely when you can talk to yourself!
