Our Fate Forsaken

After his death, Zeph became an angel, but he has no recollection of his time as a human. In the afterlife, he meets Archangel Gabriel, who is oddly possessive of him. One day, Zeph decides to visit Earth and encounters a human named Asa, with who he feels a strange connection.

Gabriel used to be his guardian angel, and Asa is still his soulmate. It's no wonder the two are strangely fond of him. Maybe too fond of him...
