does anyone know BL with emperor tops x northern duke bottoms?

Scandalous wedding. But i think bottom wasnt exactly a duke?

https://www.mangago.me/read-manga/blossoms_of_the_white_night/ correct me if im wrong

i've read this that's why I'm still looking for more..

unfortunately the bottom isn't my type since I was looking for a stereotypical historical manhwa black haired duke personality

Aww man .
Pls hmu if you find one too!!
