I haven't been able to find a Haruse fanfic anywhere, so I though I'd give it a shot. This is just a bot of drabble about what Haruse thinks of his relationship with Kuroyuri. Please enjoy!
He had always cared for him. They had always been together. He couldn't think of a time when they had been apart. His love was that of a brother, although he wasn't sure the boy he carried felt the same way. When he carried the boy he felt complete, as if a hole in his very soul had been filled. He had known him since before he was born – he was meant to protect him. Kuroyuri was the one that he was meant to protect, and the one he needed to be with. Without Kuroyuri he was nothing, no one. He would just be an empty shell that was filled with despair. Their bond was rare. They knew everything about each other and it always hurt them to be apart. When one was in danger the other knew no matter how far apart they may be. Haruse watched the pink haired boy sleeping in his arms. He watched his chest steadily rise and fall, rise and fall – it was almost hypnotic...
"Haruse. You shouldn't be daydreaming." Ayanami's cold voice crept through him. Haruse simply bowed his head as an apology in his hopes not to wake the sleeping boy. This time he watched his leader and listened to Kuroyuri. He concentrated on his steady heartbeat, and the gentle breaths he took. He could see his sleeping face in his head, his mouth curling at the edges to form a sleeping smile. Haruse wondered what he was dreaming about. He wondered if he had dreams about him, and if so what they were like. He would never ask Kuroyuri – Sama something like that, he would just continue to wonder. He wanted to stay with the boy forever, just carrying him around in his arms. He knew it was not possible, for he knew that one day he would have to leave him alone to fend for himself. No one could care for Kuroyuri like Haruse. No one knew Kuroyuri like Haruse did. Their bond was unbreakable, just like they're love. Haruse thought of Kuroyuri as a younger brother, and he often wondered how the boy he carried felt about him.
He walked through the corridors of the ship, still carrying the boy he promised to protect. As he walked he felt a hand on his face. It was small and soft. Haruse looked down at the sleepy boy and watched his gentle eyes open. They smiled at each other kindly before the boy yawned loudly and stretched out his arms. He looked at Haruse.
"Haruse. Never leave me." He whispered. His eyes closed once more as he fell back into his deep and long sleep. Haruse watched his face as the boy faded back into the land of dreams. He smiled at the pink haired boy and continued to walk silently down the ship's corridors.
