this certainly has a romance tag but the romance isn't here yet, how about give this one a try ? the mc is such a beauty, in an EERIE way

crazy female lead, there are potential love interests but no romance until the end (at least in the novel, I haven't been keeping up with the manhwa adaptation so they might have changed it)
