Just a note on the expected happy ending:
Despite sentimental music, the ending seems rather cold to me. Do they love each other at all? FL seems distant, downright cold. She rejects his closeness, doesn't want to marry anymore, doesn't want to live with him, or spend the night together.

Is this how one behaves when the beloved man, who has unexpectedly escaped eternity, returns to one? These are questions that should not be asked about a romance of desperate writers. What is worth.
