bl name help?

i read this years ago and i'm struggling to find it again. i don't remember much except it was historical (set in korea, i think?) and the love interest's name was in the title. the love interest was also chubby/plus sized. from what I remember at the end of the story they end up living together in a house by the sea. the art was also in black and white. I know this isn't the best description but any help would be amazing!
