The Moon Goddess and Her Mate

"No matter what happens to you, never marry a mortal, even if your life is at stake!"
"But why—"
“No buts! Just carry out my orders without arguing!”
Goddess Atvertha has been warned by her mother, Goddess Avtexia, to stay away from the mortal nation — a dirty, brutal, and murderous nation. The moon goddess just tried to obey, although inwardly she felt strange at the warning.
Goddess Atvertha's heart began to waver when she met a man who was dying in the forest. She, who has never known love, now feels a strange flutter in her heart.
What about the fate of the Moon Goddess after that encounter? Who is that stranger man and what will happen to the two of them?
