I love reading world-hopping novels, but there is one that I cannot for the life of me remember the name of. The premise is that the female lead travels from world to world(of course, lol). I don't recall all the worlds but the male lead in every world is the same person even if the story changes. Additionally, he always smells the same/has a birthmark in each story and that's how the female lead knows who he is. In one world, he turns out to be a male god of light while she is a worshipper (i think she is a potential Saint candidate) of that church, and she has to fight against a fake saint who has a harem of men with her. Can anyone tell me what novel this is?? I would be so thankful!
