After reading the manga I see why it has a low review. There's no plot, and as we look through the eyes of the protagonists, it's depressing. the FL is broke and has no one to depend on, and the ML is a workaholic, who's blaming himself for the death of his parents. Without a plot, as readers, we don't know when this misery will end, and seeing someone's sadness, makes you feel like shit.
The way I see it, just because there's no intro explaining everything like common isekai do, doesn't mean this one doesn't have a plot. It resolves around the struggle of the fl and ml. And looking at the story now it's quite clear where the story might goes.
A young, naive, bored, spoiled noblewoman getting out her shell and learning to actually live her life.
A stubborn, revengeful, and ambitious man who's learning to cope with his past and future.
It doesn't need dragons, royals, or magic to make it look interesting, that's the beauty of this story.
im kind of surprised so many people dislike this story. i find it much more enjoyable than the bland stories... these characters have backstories and are complex, they have solid development. much unlike other such stories where one character just falls for the other and there's some random villainess
