Percy could be accidentally caught in the middle of their relationship drama. For example, Aphrodite might use Percy as a way to make Hephaestus jealous.

Aphrodite's power of love and beauty could potentially charm or influence Hephaestus' creations.

Percy, being in the middle, might find himself affected by Aphrodite's charm but also use Hephaestus - made items to resist it.

Another idea is that Aphrodite decides to use Percy as a pawn in her game to make Hephaestus jealous, creating all sorts of romantic chaos for Percy.
