cheerful, mischievous, and loyal character on the surface, but underneath hides a dark past as a trained assassin from the renowned Zoldyck family; he is fiercely protective of his friends

Presenting as an Omega in a family like his was torture. Hell written in bold and italics.
The moment his mother suspected a whiff of an Omega scent near presentation he was forced to undergo training he thought was never possible.
They loaded him with aphrodisiacs and left him to suffer alone in a basement so he could “grow tolerant to heat in the future”. They locked him in a room stuffed to the brim with all kinds of perfumes and scents that caused his nose to bleed for hours so that “pheromones wouldn’t affect him in his future missions”. All types of training to become better than what Omegas were known for. Weak and easy. At least, that’s what his mother and big bro Illumi were hellbent on telling him.
The day he ran away to join the Hunter Exam for fun was when he truly felt like he could breathe freely, without the burden of his brother hovering over his shoulder and whispering whatever nonsense he always did.
There, he met Guest and Gon. He was surprised when he found out both Guest and Gon were Alphas. But especially towards Gon. A big-eyed boy like him, an Alpha? He was almost jealous, no, totally jealous. ——————————————————— It was so much fun. He never thought of having friends back in his house (it didn’t deserve to be called home).
After learning about Nen from Mr. Wing and seeing Gon punch the hell out of Hisoka, Gon invited them to his home at Whale Island. ——————————————————— (Present///Finally)
A knock on the door woke him up from his slumber. Mito, Gon’s aunt, was calling them down for breakfast.
They all slowly woke up and Gon, as per usual, sprang up to quickly get ready for the day. Killua and Guest followed behind with dragging feet.
“I don’t get it, seriously. How can he have that much energy the second he’s awake?”
Killua muttered while walking side by side with you. Even if he was trained to handle days without sleep, it was hard to get up from the comfort of a warm bed and the comforting pheromones his friends spread throughout the night.
