A/N: I haven't really started any new multichapters since publishing "cry of a fallen crow" two years ago. I decided it wouldn't be such a bad idea to work on a new plot idea once the bunny had invaded my mind. This is my take on the soulmate au, where one is able to see colors once they meet their soulmate. I wanted to challenge myself to study and discover more about this au world, because it isn't exactly as simple as it at first might seem. Enjoy the story and be prepared for anything and everything to happen.

Blue

I live for those who love me, for those who know me true, for the heaven so blue above me, and the good that I can do.

Everything in his sight was dull.

That's how it had always been, so Shouyou didn't find anything weird in that. For as long as he could remember, he had always seen the dull colors, the monotone world that spread open before his eyes, so it had become very mundane thing for him.

It wasn't until he had turned ten that the truth had been finally revealed to him. Apparently, everyone was born being only able to see white, black and the hues between them – he had eventually learned to name the color as gray. The reason for it was a mystery to this day. The matter had been researched for centuries, but even to this day the answer had yet to be discovered.

The one possible factor could be the soulmate-believe everyone was so fixated on. As Shouyou understood it, once one was to meet their soulmate they would suddenly be able to see the black and white world colorful. That's at least what he's been told, but to tell the truth, he didn't believe in such irrational reasoning.

What was the point of seeing colors only after you meet your soulmate? He was already 16 years and had managed to do well even if he wasn't being able to see colors. Also, what if one wasn't to meet their soulmate and their world would remain dull for their whole life?

He simply couldn't understand what was so romantic about the whole thing.

Shouyou was rushing home from volleyball practice. The more he had learned about the soulmate stuff and colors, the more Shouyou believed he was happy how things were at the moment. All he truly needed in his life was his loving family, his precious friends and volleyball. With that just, he could imagine marrying a beautiful woman and having children with her in the future.

That's the conclusion Shoyou had come to and that's what he was striving for. He didn't need anything else; no color, no soulmates. His daily life was already filled with happiness and loving people.

The boy made a turn at the gates only to see from the corners of his eyes that he was heading towards a person. The ginger tried to stop his advance, but reacted too late and ended up crashing at the person.

"I'm so sorry." Shouyou apologized, massaging his nose. He then opened his eyes and saw an unfamiliar scenery. Instead of typical gray world, various colors danced before his eyes making it difficult to fixate his eyes on something. Shouyou was scared of this unknown sensation that was welcoming him and shut his eyes, hoping that everything would return back to normal once he opened them again.

"You should watch where you're going, dumbass." A sombre voice spoke, bringing Shouyou back to reality. The boy squinted his eyes, relieved to find out that everything had returned back to normal. Once this matter was confirmed, the boy pursed his lips.

"I DID APO-" Hinata lifted his head to glare at the male who was at least head taller than him, but froze once their eyes met. Once again he was facing this unknown sensation. Instead of the typical gray, this boy had eyes that despite of his dark scowl, were such peaceful and tranquil. They also had a certain aspect of coldness in them, but it was hidden beneath the waves of the calm yet playful stare.

The longer Shouyou stared into the eyes, the more they were sucking him into their sparkling world. The ginger was completely dazed, hoping he could stare at those eyes of an unfamiliar color for the whole day. In his whole life time he had never stumbled across anything so beautiful.

But Shouyou also knew that this was the first time he was seeing other color than of those typical white, black and gray.

The moment he realized this, Shouyou shook his head and dashed away from the boy while mumbling apologizes between his breath. The ginger made sure to look down the whole time he was running. He didn't like this new affair he was facing and wished that everything would return back to normal. He liked his life as it was and didn't need any breathtaking events to destroy everything he had tried to build for so long.

"What a weird guy," a male next to the person Shouyou had crashed against, chuckled. "But his eyes were beautiful." He then continued, glancing at the person next to him. The boy with cropped black hair and blue eyes stared into the empty space where the ginger had stood moments ago.

"Indeed. I don't think I have even meet such radiant pair of brown eyes. I thought he would burn me with that intense stare of his." The raven commented, looking abashed. His companion raised his eyebrows in surprise. He had never seen the boy looking so lost.

A vivid laugh echoed at the school gate. "Never mind that, we were about to check out the school. Come on, Tobio-chan." The brunette then continued heading inside the gates and to the school yard.

The raven flashed a murderous scowl at the brunette. "Haven't I told you to stop call me that, Oikawa-san." Tobio murmured, clearly displeased of how the older male was calling him.

Despite the fact that Tobio was emitting rather dark aura, the brunette didn't seem to take this into notice. Instead his expression seemed to fall as he furrowed his eyebrows. "And you should stop acting so cold toward your older brother. We're going to share the same surname so I won't know who you're calling, Tobio-chan."

Tooru wasn't exactly the first person to change his behavior to please others, and Tobio knew it. He hated the irony of fate that was obviously playing with him. Just when he had thought that he could throw that guy away from his life by choosing another school in a completely different prefecture, he was suddenly being pulled to him even closer than before.

Tobio didn't understand why the fate was being so cruel to him. Why bad had he done in his previous life to deserve this? The raven let out a deep sigh.

"Oh, why such a long face, Tobio-chan?" Tooru teased the boy, but Tobio was too tired to argue with him. He could only wonder how he would survive living with this person. Tooru was sure to drive him insane faster than light managed to travel in space.

Tooru obviously came up with something, as his face suddenly turned into a wide smirk. "It must be about that boy we met before? You have nothing to worry, my brother! That boy came running from this direction, so he must be a student of this school. Don't worry, you're sure to meet your sunshine again."

"OIKAWA-SAN!"

"Eeh, who is that? Do you know someone like him? If you know, then be sure to introduce him to me next time. I want to meet everyone who could be your possible partner."

Tobio clenched his fists.

Oh how much he hated this man.

His heart was beating fast, his stomach was aching and he barely managed to breath. Shouyou stopped at the front door in order to catch his breath. His stare was glued to ground. Shouyou was afraid to look around him, fearing he might once again see another new color.

He didn't want it.

He wanted everything return back to normal.

What had he done to deserve this?

"I'm home." Shouyou mumbled as he entered the house. He had barely managed to take off his shoes when a small figure ran to the entrance and ducked into his arms.

Natsu laughed happily as she embraced her brother. "Welcome home, Onii-chan!"

Shouyou showed her a weak smile and ruffled the girls head. Natsu showed a sings of pleasure and rubbed her cheek against his chest like a cat. It was weird, but Shoyou had learned that this was her way of showing her affection.

"Welcome home, Shouyou." The mother greeted her son, once the siblings had made their way to the living room. "The dinner is ready. Do you want to eat?" He had just returned home from intense training so knowing the typical Shouyou, the boy was starving for food.

"Ah, yes." Shouyou's answer was pallid, so the mother started to wonder if everything was alright with her son. He seemed to have lost that usual brightness of his. His behavior was so unlike him.

As they sat down to enjoy their dinner, the mother finally made up her mind. "Is everything alright, Shouyou? You seem little down." She questioned, knowing by now that something had definitely happened to her son. If nothing else, then it was maternal instinct.

Shouyou tried to think of way to dodge the topic, but knew that he couldn't lie to his mother. It was the best to tell the truth. "You know, today I saw colors other than white, gray or black for the first time in my life." Even now his words seemed to have no energy in them.

The mother dropped her chopsticks as she covered her mouth with her hands. Tears rolling down her cheeks she went to hug her son, caressing his head. "I'm so glad for you, Shouyou. I'm so glad." Her words of relief escaped into the air.

Shouyou sat silent as his mother kept of embracing him. As far as he knew, his mother had once been able to see colors as well – meaning she had met her soulmate. Unfortunately, he died of cancer not long after they met and she became unable to see colors again. Her world turned back to the dull, monotone and gray one.

That's how the world worked. Once you were to lose your soulmate, you would also lose the colors in your life. She had eventually met and married their father and given birth to two healthy children. Her only regret was that she no longer could tell what colored eyes and hair her children had. She was left to wonder if her children had inherited her brown hair.

"What's so odd with that? Natsu also can-" The ginger haired female suddenly froze.

"What?"

"Natsu also can embrace Onii-chan!" She continued all of a sudden and hugged Shouyou hard.

Feeling his mother and sister embracing him, while showing their affection, the swollen up feelings inside Shouyou suddenly burst like a billow. The young male cried his eyes dry in the arms of his mother and sister, being unable to condone the overwhelming feelings inside him.

Shouyou didn't remember when it had happened, but apparently he had fallen asleep while crying. His mother and Natsu had carried him into his room and covered him with a blanked. Giving a small kiss on the forehead, the mother had wished all the best for her son.

That night Shouyou had seen a nightmare. He was in a completely unknown world, various colors flashing before his eyes driving him insane. Just as he was about to break mentally, the male he had crashed against earlier than day, walked to him and took hold of his hand. He was once again enchanted by the color of his eyes.

The color he would later known to be called blue.
