I understand

"So what will you do now Nico?" Percy Jackson asked, approaching a dark haired boy with his girl friend beside him.

"I think I'll stay here. I'll still play messenger between the camps though. Be ambassador of Pluto." Nico Di Angelo said.

Percy just hummed.

"Actually, I need to talk to you." Nico blurted out.

"We are talking." Percy said.

"I mean alone." 

"You two talk. I'll go and see if anybody needs any help." Annabeth Chase said, kissing Percy's cheek and going.

"So. What do you want to talk to me about?" Percy asked.

"I-I-I had a crush on you." Nico stuttered.

Percy's eyes widened in understanding.

"Oh Nico." He sighed.

"I know you are probably going to hate me now, and I just want to say I'm sorry." Nico said in a small voice.

"Oh Nico, don't worry. I understand." 

"What?" Nico sniffled.

"I don't hate you. You are human, and love is love. We can love who we want." Percy said softly.

"I don't get it." Nico said.

"I had a crush on Luke Castellan. Apollo is pretty hot. Don't even get me started on Tristan McLean" Percy said, winking at Nico.

"Wha- But you're dating-" 

"Annabeth? I'm bisexual man." Percy said.

Nico couldn't take it. He burst into tears, and launched himself at Percy. Percy just held him, comforting him.

"I'm sorry" Nico repeated over and over.

"Don't be sorry for who you are, man. Don't be." Percy said.

Nico just hugged him tighter.

"You, need to go to the infirmary. With great power comes great need to take a nap. Direct quote from you." Percy said.

Nico gave a teary laugh.

"Now come on. You're gonna be taken care of by a blonde haired, blue eyed hottie of a doctor." Percy said, winking and dragging him to the infirmary.

"Should we be worried?" Annabeth asked, looking from a distance.

"If Nico told Percy what I think he told, they'll be fine." Jason Grace said, smiling at their direction, adjusting his crooked glasses.

Piper sighed, looking at Will Solace fussing over Nico, Percy winking often. 

Love is great. Familial or no.
