Gender
Nico knows things would have been easier if he had been born a girl. They wouldn't have to withstand some of the glares they get in public when Percy grabs his hand. They wouldn't need to worry about being judged. That's why Nico occasionally decides to curse his gender. But Percy tells him that he loves him so sweetly. Tells him to stop worrying. Being a guy is part of being Nico and he loves every little part of Nico. That he can't imagine Nico as a girl, not really. Besides, he says, that they don't need to care, if the rest of the world doesn't like that they love each other, it's not their problem. All Percy wants is Nico. Their parents are happy for them, their friends too, and that's all that matters he tells Nico. And then Nico stops thinking about his gender, instead focusing on his Sea Prince.
