Perhaps a plot could revolve around a love spell gone wrong. Aphrodite, being the goddess of love, might accidentally cast a spell that affects Poseidon. At first, he is angry about this intrusion into his will. But as the spell's effects make him see Aphrodite in a new light, he starts to question his own feelings. They could then be forced to deal with the consequences of this unexpected situation, not only among the other gods who might be watching and gossiping but also in terms of how it changes their relationship with the mortal world. For instance, their combined powers could cause strange weather patterns and erratic behavior among the mortals in love, and they would have to find a way to reverse the spell while also exploring their new - found feelings for each other.
One possible plot could be a love triangle involving Poseidon, Aphrodite and another deity. Maybe Aphrodite catches Poseidon's eye, but she is already in a relationship.

Poseidon could be depicted as a somewhat lonely god. Despite his power, he lacks the warmth and connection that Aphrodite represents.

She would be in control of her own actions and decisions, and her relationship with Poseidon would be a balance between her own desires and the expectations of the divine world.

One idea could be that Sally discovers a hidden power within herself that is somehow related to Aphrodite.

This could lead to a friendship where Sally has to learn the ways of the goddess's domain.
One idea is that a new god or goddess emerges who is a combination of beauty and wisdom, and Athena and Aphrodite feel threatened.

A plot might involve Hephaestus creating a magical item for Aphrodite as a gift. This item has the power to make her see the world from his perspective.
