It's revealed at other chapters that she did came from another world (like reincarnated) and because of that she became a saintess. Then, there's the mc who's a "transmigrator" that makes her a possessor of the og robelia's body. Idk if this is right but that's what i understood ( ̄∇ ̄")
Im I missing something or not. Why do they accept the Korean concept on ch. 20? Does the consort came from another world?
