They had won the war. Gaea had been defeated, and everyone was happy.

Well, almost everyone.

Jason Grace sat on the mast of the Argo II. Hope Nico won't mind me taking his spot. Jason thought, with only a hint of sarcasm. Usually, Nico di Angelo was sitting up there. Right now, however, Nico was on the deck with his boyfriend, Percy Jackson.

Percy and Annabeth had broken up about two weeks before. Jason, being a good friend to Nico, had helped him tell Percy about his true feelings. Unlike what Nico had expected to happen, Percy was ecstatic. Apparently, Percy had been trying to figure out how to tell Nico the same thing.

It doesn't take a genius to figure out what happened next.

Now, the Son of Jupiter sat, watching from above as Percy ruffled Nico's dark black hair. He watched as Nico attempted to get away, only to fail, and end up wrapped in Percy's arms. He watched as the couple laughed. He watched as their faces got closer, only inches apart. Their noses touched and-

Jason looked away.

He wasn't sure why, but seeing Nico with Percy made him feel uneasy. His stomach turned. He felt slight rage, and what he assumed was jealousy. When he looked at Nico, he would find himself blushing.

Nico, with his pale complexion and dark, shaggy hair. Nico, who would argue or curse in fluent Italian when he was angry. Nico, the son of Hades, who could raise armies of the dead within a matter of seconds.

Nico di Angelo, who Jason couldn't have.

He looked back at the two on the deck. They were laughing, Nico still wrapped in Percy's arms.

Jason gritted his teeth. Why? Why him? Why did he have to fall in love as soon as he couldn't have the younger boy? It wasn't fair.

Love is never fair. Cupid had warned. Jason remembered that day. Cupid had forced Nico to confess that he was gay- and, more importantly, gay for a certain son of Poseidon. Nico began to fear rejection- surely the others would only see that as another reason to hate him. Jason was there, though. Jason was a shoulder to cry on, he was a friend.

He was like an older brother.

When Percy and Annabeth broke up, Jason was nice. He helped Nico get with Percy, and it worked. His plan worked, and now the two were a happy couple, laughing and kissing on the deck of the Argo II.

This wasn't supposed to happen, Jason thought unhappily, I wasn't supposed to fall in love.

As he continued spying on the two below him, he sighed, resting his chin on the heel of his hand. A single thought replayed through his mind, a personal mantra of depression.

I guess my plan backfired.
