I think they’ll move to human world after the marriage
Then make sure that Naira visits the human world and then the whole game after the wedding, she was with the main character at least please. For me, Naira is a ray of good sun that needs to be protected and not let anyone offend her. Can you also make it possible to sleep with the queen and her daughter Ana, who was watching her at the beginning of the game? Also, to meet Irena again, who stole the crown at the beginning of the game because I saw in the text, you can say a hint and a reference that she would want to fool around with him again
