Probably no romance ending even the demon lord don't have any wives, I mean the white hair only political relationships and the MC is very good old man in soul not dare to touch a young girl or fall for enemies seduction.
Lol they both become his wife much later on . They are all adults by then though.
both of themm??? are u serious? （/TДT)/
Them asking for romance/FL to manhwa whose MC is a reincarnated old man purely prove how disgusting they are for favoring pedophilia. Like, shut up. Just enjoy the story with pure action and storyline.
None of the girls are children so it's not pdfile but ephebophile which is also wrong. But the relationship starts when both are adults.
so who's the fl?
