I heard spoiler that the book is elzay's actual first life (her life as a korean girl is her second life, the god put the memory of her first life in a book form) (so aseph is a real person from her first life, not just a book character), so this new memories that overflowing to her in the end of this chapter is her first life memory

idrk but i think its more like the mc was originally pink's twin already but was killed off in childhood for whatever reason and it just never came up in the book she read, and aseph mistaked pink for his pair bc theyre similar (?genetically? idk probs just trying to sub mc). Then after she died she lived her 2nd life in korea, then came back to her first life's world but in the timeline(?) that she didn't get offed in to become a pair with aseph and honestly, just pure speculation bc i dont remember first few chs anymore if it could explain it, or anything specific to back it up but author (of webtoon) might add in that aseph big sad sad when die with no lover that god either brought back his pair (mc who was his orig pair that didnt live long enough) to prevent him from being big sad sad or idk destroying the world w his big sad sad spirit. (idk how to explain this but it happens a lot in webtoons and i have a feeling this will be given as an explaination)
Was that mark placed on her so she could remember her past life . Now it makes a little more sense why her dad mentioned the mark is rare and how it was unusual that both the sisters had it...
