Can't find the novel!

I've been searching for a whike now. I remember I stumbled upon it while scrolling on tiktok. Don't really remember and find what it's called, but no luck so far. All the details I remember, was that it had not chinese, but more south asia vibes, it wad arranged marriage with a princess from other kingdom, she was stubborn and didn't take her facemask off, and after a while it turned out to be a dude, the older dude was pretty dark skinned in the art, and the "princess" which was married off to him, topped. So younger top. Thats it. Maybe a little, but I can't remember anything else Thanks for any hell
