But the ML is definitely a northern Duke! Or his territory is in a really cold, barren part of the kingdom. I think the FL travels back in time, but I could be wrong bc I’ve read so many stories like this that they’ve all just kind of jumbled together in my head. All I can really remember is that she “discovers” a cave in the mountains that contain either really powerful magic gems or like a source of magic. It’s also in webcomic format if that helps!
I don’t remember much about it other than this guy asks the MC to be his model (or asks MC to be his photographer? Ask MC to be the artist? I’m not sure) for makeup and they enter a competition where their supplies gets sabotaged and they take a black and white photo using green lipstick for the theme “red”. It’s driving me insane, someone please end my misery! TTwTT
