I was a little concerned bc it's shown early on that MC transmigrates and is seriously OP, and tho the plot can waffle at times about why she can't always go full out with her powers or how it doesn't solve everything, it still is able to tell an engaging story while giving the MC believable (and some even relatable) obstacles to overcome.
I also appreciate how MC near-phenomenal cosmic powers are given their own intrigue. We don't know where they come from at the start (tho we can guess) and we find out later that she isn't as completely OP as we're first led to believe.
I also rather enjoyed how the author went a bit tongue in cheek with acknowledging how the MC was Mansa Musa-ing the economy with her ability to create as much currency as she wants out of thin air. But I can see the issue abt how the author makes the MC deal with slavery become a hit or miss with readers.
I do want to clear up that, despite what another commenter says, it's shown clearly that MC did want to use her powers to just free everyone. Multiple times. And multiple times, she only didn't bc she was convinced to go along with another person's plan, which was more thought-out and better set-up to break down an entire slave system and reform a whole society, rather than just save a single group of people for the time being if MC did things her way. Whether or not readers will agree that going along with this plan was the best way to go abt dealing with this issue, is another matter.
The story also emphasizes that MC cannot replicate magic items. Most likely, this implies that she's also limited in other ways of what she can do with magic items, and that pretty much sets up the context clues that the slave keys/collars are some kind of magic item.
And I also like the directions the author is choosing to focus on for her story. I think it better fleshes out a world when the romance isn't always in the forefront of a romance story, and here, all the main cast are pretty dynamic in their own right (well, except for most of the villain side-characters ig).
It's clear the author is going to seriously explore the whole transmigration aspect to the story, rather than just hand-waving it away, bc the MC is alive in her "real" world and does manage to return against her will. The way the author dissects the MC's mental process as she struggles to find somewhere to belong and her fears in losing that place is being well written, imho.
And I quite enjoy the obstacles the main couple faces, even with the introduction of imprinting (bc it explores how harrowing such a feature is for everyone involved--take that, Twilight /jk).
Tbh, I'd be happier if the ML had more interests in things beyond the MC bc there's a lot of potential with his situation. But idk if we'll get to see it bc the MC also has a lot of different focuses the author is setting up for her and all of those look like a lot of fun to explore as well (I'm most interested in seeing more abt the MC's new family, particularly as the mom/dad/sis is set up to be fascinating bc of hints that things aren't so clear cut in the family dynamic--tho the other wives and half-siblings are rather one-dimensional).
Definite recommend for ppl interested in the whole transmigration into a magical world novel genre.
