I'm guessing the outcome of this based on my half ass knowledge of phantom of the opera,but
I'm assuming what she meant by him saving her, possibly having something to do with her mother because Christine( the heroine in the novel ) wanted to become a better singer for her dead father sake and ask for help in the backstage of the theater
But in this case its the reverse, I suppose, though I am surprised that Erik (the phantom ) isn't acting like an incel though
then again
Based on the fictional character we have seen so far, all of them have a pretty end of story state and understanding of the fact that they are fictional
