I think there is quite a lot of romance for the genre, but it's well hidden behind the action parts.
We have FL's hallucinations/past memories of a "grand duke of winter", since she likes a lot the trope in romance manhwas. I don't understand if he is referred to the silver haired mentor of the white haired villain who was her past lover.
It's already implied that she could have a story with the regressor too, although I think they have 0 chemistry.
But for a story where each time something happens, it has to do with her past lovers, I think it's wrong to say that there is no romance.

I am right now in chapter 40 and so far there is no romance. I was wondering at what chapter or if there even is romance in this mahnwa.
