Good interpretation. Close but not quite.

The narrator and Aphrodite fall in love and, after a year and a few days make love for the first time. Almost a year and a half later, she leaves him for the thief. She hurt his heart until his wishing death. Then, in the end, her new lover, her old lover and her brother die and she kills herself in the end because she choose herself over love and others.

True story until the prophecy begins.

Also, she may be saved. But she'll never have either lovers again. She must choose neither to live.
