Basically she unalives herself. Remember her saying she will kill anyone he loves and since he loves her she kills herself.
In the after stories it's mentioned he died of old age and was unmarried. And once he died he comes back to his childhood time and meets Fl there and asks something and she says he is her fiancee. Then he decided to live a loving life with her.
