Y’all what does rofan mean? Also any mangas/manhwas like death game?

It's an abbreviation for a fusion genre: Romance and Fantasy. It's "로판", short for "로맨스 판타지"in Korean. (taken from reddit btw)

That makes sense thanks
Never heard of it before

no problem! Honestly I have not either, but it is pretty interesting to learn about these kind of words and what they mean
