(You have to be patient though I think at least 30 chapters? I forgot) (+ Hopefully you haven't read it yet)
Like yeah but that's the thing that makes it good
I actually don't like harem too, but this one had to be harem to be good
Anyways the first 30 chapters or so, are like the introduction, after that the plot begins, actually I'm a lot picky when it comes to straight romance (just saying) so this is one of the few that I like, hopefully you'll like it too.
A lot of men pine for her but it’s not a harem unless she ends up with multiple guys, no?
Anyway, here’s my recos (dark romance, fed up FL)

Any recommendations for historical manhwa where the fl wants to die? Or fl who is fed up with everything and just accept her ill fate?
