For anyone who is deciding whether to read this or not:
If you want a flawed FL and ML, this is it. The FL isn't naive for the sake of creating drama. The ML isn't an asshole for the sake of being one. These two characters are far from your typical leads, but that's what makes them refreshing. I hated both of them but I continued reading because I think there's a lot of potential for them to grow. The story is more realistic than your average historical manhwa. There's no isekai, no reincarnation, no time travel, and no foreknowledge, so there's no convenient/easy fix to the FL's problems.
The story itself gives me Pride and Prejudice and Emma: A Victorian Romance vibes.
