Male lead*
This is exactly what I started thinking the moment they started hinting at a romantic interest's presence! I think the story is progressing very well without an ml
I feel like it would be confusing too, with the FL being the grand duchess and I'm sure the ML is someone important (based on the clues; margrave bowing, goldwester merchant can't say no to him, nata realizing his aura, etc),
who's gonna be part of whom's family and the political disputes around it would make this manhwa less relaxing and appealing to me tbh
I won't lie, I would like it if the fl had no romantic interest. They've been hinting the ml here and there and I've been enjoying the story perfectly fine just like this. Thinking about having a ml for the fl makes the story more boring(?), not sure how to word it. I like the story the way it currently is and adding a male seems like it would ruin it for me I guess.
