The core of the show centers around a "OP" protagonist trying to understand the world he's in and maybe get home (no shock) but the difference in this case is how he handles it.
Overall he's avoiding making major waves, careful in most instances to hide what & how powerful he is and when cornered underplays his part giving others credit. Again not reinventing the wheel but handled fairly well.
The majority of the show seems to center around how the protagonist is handling his interactions and individual relationships and mostly subtle attempts to try and change the world views / prejudice of those in the same world.
Although it's technically in the Harem category and does give some "Fan Service" in a few instances the reason for the women following him make sense. It's a feudal world and a "man" (he's roughly 15 in appearance) who's not treating those under him horrifically (power wise, servants and spaces) and treating women as equals is unusual and would be a draw logically.
The few "Fan Service" moments aside he's going out of his way to avoid inappropriate interactions / allowing his female companions to make sexual advances and instead is making a safe environment for them.
Add in some moments where the character struggles with some real concerns (before he's lost in the enjoyment of the new experience) and it's an above average anime.
However it won't appeal to all due to the lack of action in every episode, the focus on relationship building etc.
Genre's are Fantasy, Isekai and Harem
