Spoiler
I'm just going to share what I remembered. However, since it was already some time since I finished reading the novel, I might have forgotten some details.
In addition to what is said, the true Yvonne is somewhere in the mirror with Vinter (Winter? Dunno but names keep on changing ╮( ̄▽ ̄)╭ ). But this Vinter is like the original Vinter from the first timeline. You see, the events keep on repeating. Real Yvonne dying and getting possessed before she is discovered. Penelope dying over and over again. That evil b*tch Leila winning ang destroying everything. Then Vinter rewinding it from the start to try to save people again. Eventually, Penelope's soul broke and scattered to pieces (I mean who wouldn't? Experiencing the same torture over and over again and dying). A piece of that soul came to the modern world-that is our MC. So essentially, our MC right now is really Penelope.
Anyways, I hope they draw the side stories too since this will be explained in that part. And they had a happy ending too.
Spoilers? What happens I need to know how this plays out, is the 'real' daughter just a fake?
