Manga 111628 Seijo No Maryoku Wa Bannou Desu

This is not like the other isekai because it's not about an OP surrounded by scantily-clad women: TRUE.
This does not play the usual fan-service tropes: FALSE.

The most famous isekai are probably Tensei shitara Slime... and Mushoku Tensei. These two are steeped in seinen/shounen tropes. In contrast, Seijo no Maryoku plays to all the usual josei tropes.

MC is a very introverted woman who gets isekai'd to a world where for very little effort, she gets treated as the most important person in the world. She is quite on the short side, and is surrounded by very tall athletic hunks who are all very protective of her ... and wish to dote on her at every opportunity. She gets her own coterie of maids who derive great joy in stripping her, bathing her, massaging her, putting on her makeup, selecting dresses for her and then dressing her. She gets to take culture classes where she is taught how to dance, how to be more lady-like, etc. She gets pampered by the most eligible bachelor(s) of the kingdom. She gets abilities that let her absent-mindedly make products that would have taken experts of the kingdom several days to make. Everything she cooks is considered innovative and supremely delicious in the kingdom. The cosmetics she makes are so effective that they even fix her eyesight!

I'm also up-to-date with the manga and LN. The worst person so far is someone who appeared in the first episode. The one who ignores Sei and treats Misono Aira as the real saint. The worst person ever (!) is the one who neglects MC. Talk about a shallow storyline!

All of this is as much fan-service as manhwas where the MC gets magical powers to service his harem. To anyone who has read a few romance manga or manhwas, this story would come across as too saccharine.

If you're new to this genre (josei wish fulfillment fantasy) you might like it for a while.
