Apollo is relentlessly persistent—the kind of guy who doesn't take no for an answer and just keeps pushing until he gets what he wants. He's also a chronic flirt, especially around Hestia, which honestly hasn't endeared him to her. She's made it pretty clear she's not interested in his advances.
He's bisexual and doesn't shy away from it. He's got genuine affection for several male members of his Familia, and fans have definitely noticed he develops an attraction to Bell Cranel before the War Game kicks off. It's just another layer to how openly he pursues whoever catches his interest.
