A more mature take on the isekai genre, this is a welcome change for those tired of the hero read trope, still, there are some things I find rather lacking, for example, the pace, there is little going on, and I don't mean action, even interesting dialogues would do, there is some intrigue at play but it doesn't play out and is kept at shallow levels. Another example is the little impact the knowledge of this world is making, he had time to take whatever he wanted from this fantasy world, are you telling me he didn't even install an encyclopedia in his laptop? If it was me, let alone the encyclopedia, I'd be sure to pack all the information he could gather on science and medicine and crafting, I'd take precautions to avoid misuse but I definitely would take them. In any case, he took electricity and many gadgets, that alone should be ultra revolutionary yet the Queen just comment something on the light-bulb... What brings a big change to the country? glass marbles... nop, not joking
In any case, the MC is different from the usual guy high on his own power that collects women only to not touch them. Right off the bat the MC is there to marry and thus he actually has proper relations with a woman and even seams like a loyal fellow. Also, he's a proper grown-up, someone who knows the hardships of a life as a salary-man and chose this new world to his previous life, so he acts accordingly, unlike other such settings where the MC's mind seams to revert to their adolescence instantly, ej. "Tensei deshitara slime...". As for the female lead, she's a decent char I guess, I like how she keeps checks on the MC to see if he's a hypocrite, and some of the more conflicting things are probably because their society is highly male dominant society. Actually, the story might have been more interesting told from her perspective.
Story-wise, so far it's been rather uneventful as I say above, the intrigue goes nowhere, there are few problems or they are just explained lengthy just with words and then forgotten, as of now it's starting to move forward so it's too soon to tell, so far kind of boring other than the relation of the MC and female lead.
Other than that, art is good, dialogues a bit lengthy but decent and the relation of the two main chars is good enough imo.
So overall, an interesting take which I need to see more to make a proper opinion but so far, not bad.
