Several characters have had crushes on Percy Jackson, most notably Annabeth Chase, his main love interest, but also Rachel Elizabeth Dare, Calypso, Nico di Angelo, and Reyna Ramirez-Arellano, with varying levels of intensity and duration, often stemming from his bravery and kindness.
In TLO, Rachel admits that she had a crush on Percy since he introduced her to the "Olympian World." Nico said he fell for Percy because of his bravery. Calypso is cursed to fall in love with the heroes on her island, but she was also attracted to Percy's appearance.
Percy's oldest romantic relationship is with Annabeth Chase. Their relationship gradually changes throughout the first series, with the goddess Aphrodite first insinuating that it was romantic in The Titan's Curse, when Percy undertakes a quest to free Annabeth from the Titan Atlas.
Nico di Angelo had a crush on Percy. It was revealed in the fourth book of the series, The House of Hades. Though it is made clear by the end of the fifth book that Nico has gotten over Percy and moves on.
Will had kissed Nico for the first time in a moment of impulsiveness, something Nico didn't know Will had in him. The kiss had been just like this one, short and sweet. Then Will had pulled away, worry on his face, an apology tumbling from his lips. Nico had stopped him.
In The Battle of the Labyrinth Clarisse shows strong feelings for Chris Rodriguez and shows her kind and caring side to him, even before he becomes her boyfriend.

Poseidon states that Percy has surpassed all heroes including Hercules (much to Zeus' annoyance) and afterwards gives Percy a hug to which Percy starts tearing up (as it was the first time his father had ever hugged him).
And Percy, well… I think he subconsciously had feelings for Annabeth all along, but was clueless on the surface, until the Titans Curse, when he had all the feelings after she disappeared. And yes, Percy definitely was jealous of Annabeth's feelings for Luke.
Before he could say anything, Thalia closed the distance between them, kissing him with the same fierce energy she carried into everything else. Percy's eyes widened in shock for half a second, but his brain caught up quickly enough. He kissed her back, his hands instinctively finding their way to her waist.
Luke Castellan. Luke Castellan is a Greek demigod son of Hermes and May Castellan. He was one of the main antagonists of the Percy Jackson and the Olympians series. He was tricked by the Titan Kronos into hosting his spirit.
Leo Valdez is the most hyperactive among ADHD kids. He literally bursts in flame whenever he gets excited. In the Heroes of Olympus Series, their good friends from Camp Jupiter also have ADHD, however, they have more self-control and fewer attention problems because of their military training.
Clarisse is a curious, perceptive 17-year-old who questions societal norms in a world where independent thinking is discouraged. Unlike others in her society, Clarisse appreciates nature, engages in meaningful conversation, and observes the world around her with childlike wonder.
Children. Hermes has many children and all undetermined children go to Cabin 11 as explained by Luke in The Lightning Thief. His favourite child is Luke Castellan who he loved so much to the point he became his pride and joy, according to Poseidon told Percy in The Titan's Curse.
