Errr.... I don't get the ending. Please explain it to this idiot me. TT. TT

Raeliana is staying in this world with Noah for good, but the narration was just of Noah's thoughts and he meant that even when they grow old and die and Realiana is reincarnated into her original world again, even if they're both different people and she doesn't know him, he will still find her.
So when he mentioned the Goddess coming to retrieve her soul he was talking about the day when she actually dies, probably from old age, that's why he said a long time from now.
Kinda spoiler
Im back here from not really reading the novel and want to say that rashta is a fcking selfish piece of trash as well as the emperor. Fcking rashta's very threatened at the empress just because she can't beat her like guuuurllll you are nothing like her. And just because you are pregnant you become ambitious. For all we know that kid inside her is not really the emperor's child because we clearly know that the infertile one is Sovieshu and not Navier. So trashta just i dunno? fcking die ig.
And also Soviesu right after their divorce and Navier's remarrying Heinley he fcking locked the two, well he plan to release heinley but not Navier because that shitty trash still want Navier by his side and expected her to be by his side even though he's outright cheating on her. Duuuuuude she doesn't belong to you. The moment you brought trashta inside the castle and treat her more than Navier is where you mesed it up already.
