Obviously, Percy is one of the main characters who would interact with Aphrodite. He might be initially confused by her attention and then gradually become more aware of her feelings.
Annabeth could also be an important character in these interactions. As Percy's close friend or more, she might sense Aphrodite's intentions towards Percy and try to protect him in her own way. She could be very suspicious of Aphrodite's actions and constantly be on guard.
The other demigods from different cabins would surely interact with her. For example, the children of Ares might initially be at odds with her because of the differences between their cabins' natures. But in the face of a common enemy, they would have to put aside their differences and cooperate. This could lead to some interesting character dynamics and growth for all involved.
Percy is the central figure, of course. But in many fanfictions, Aphrodite herself plays an important role. She could be the one setting the trap, or she might have a more complex relationship with Percy where she's both the antagonist and a potential ally in breaking the trap. Grover could also be involved, using his nature - related powers to help Percy in some way.
Perhaps there is a plot where Aphrodite has to choose between her feelings for Percy and her loyalty to the other gods. The other gods might not approve of her having feelings for a demigod like Percy. So she has to figure out a way to either hide her feelings or find a way to make the other gods accept it. This could lead to a lot of internal conflict within her and also some interesting interactions with the other deities.
Piper McLean could be a great addition. Since she has some connection to Aphrodite already. She could either help Aphrodite in her plans or try to protect Percy from her. And of course, we could add some minor gods or goddesses like Eros. He could be Aphrodite's little helper in creating chaos with love arrows, which would definitely fit in with the lemon aspect of the fanfiction if it involves some love - related mischief.
The main characters are Aphrodite, the beautiful and powerful goddess, and Percy. Percy is a key figure in the demigod world, and when Aphrodite falls in love with him, their interactions become the focus. There may also be other characters like Percy's friends who might react to this strange relationship or other gods who have opinions on Aphrodite's newfound love.
Annabeth could be quite popular. In some fanfictions, she might be jealous of Percy's connection with Aphrodite and this could add a lot of drama to the story. Her intelligence and strong will would make her a force to be reckoned with in the love triangle situation.
They might interact with a lot of tension. Since Aphrodite is all about love and sensuality and Artemis is about chastity and the hunt, there could be a natural friction. Maybe Artemis is constantly trying to avoid Aphrodite's attempts to involve her in love - related matters.
Aphrodite herself is the main character. Also, her lover Adonis is important. He was a very handsome mortal man. Another is Hephaestus, who was Aphrodite's husband in some versions of the story, even though she had affairs with others.
Percy Jackson himself is extremely popular as he is the main character of the original series. Fans love to write about his interactions with Aphrodite. Aphrodite is also a popular character in these fanfictions as she brings the element of love and beauty. Annabeth Chase often appears as well, especially in plotlines where Aphrodite's actions might interfere with Percy and Annabeth's relationship. Grover could also be a character that shows up, usually as Percy's supportive friend during the events that are set in motion by Aphrodite - related fanfiction plots.
Obviously, Percy would be one of the main characters as it's a Percy Jackson fanfiction. And Aphrodite herself would be a key character since it's her challenge. Annabeth could also be involved as Percy's girlfriend, and her wisdom could play an important role in helping Percy face the challenge.
