Person A is a life god, stolen from their pantheon as a young child, due to the pantheon that kidnapped them needing a life god among them. But Person B, a child god, the same age as Person A, who’s the god of a forest, ends up falling in love with Person A as they get older, and vice versa. Person A decides to stick around Person B’s forest to spend time with them, helping the forest remain fertile and full of life. But then a stranger comes, from Person A’s true pantheon — and claiming to be Person A’s betrothed since birth.
