Hello everyone, nice to meet you guys, I'm shirotani and welcome to my first YOI fanfics~
First things first, to those that are reading my other stories too (hopefully there are some) 2k16 wasn't exactly the best year for me... (≡人≡；)
As in I'm glad it's over! I'll be continuing some of my unfinished stories, but have decided to delay them some more for now in favor of this fanfic... And no worries I already wrote at least 9 chapters for this fanfic that still need lots of editing, but they are here so definitely will be updated soon!

BTW thanks for reading this cheesy stuff in advance and no worries it will be a little different from the other soulmate Aus.
Thanks already for those supporting me and have fun reading~~ (ノ_．)

Disclaimer obviously don't own this series (sadly enough)

Prologue

The question would be, when did it appear and where did it start? Had it been there when the earth started turning around the sun or had it started when Eve took that one bite from the forbidden apple.

The answer was simple it had been there since the beginning of time, a mysterious intervention of God is what many liked to say. It was strange yet always felt so natural and just so right. There was no science to it, no prove or anything else. It was like debating the existence of a god itself, an unending battle.

That moment when the first cries of a newborn made its way into the world and they saw the light. A new world in which they would surely find it no matter what circumstances, their very own soul mark.

A special mark on their body, a mark that would only receive a real meaning once they were completed. Completed in this world could mean only one thing, the moment when two soulmates bind together for the first time. It might sound cheesy and really like any overused plot written by some teenager desperate for some romance, but really that's just how the world worked like.

If it was a blessing or a curse, it all depended. As they liked to say 'case by case'. This was a gift given by the gods and could be either turned into something unexpected as some might have experienced.

However everyone was different. Either they were born with a soul mark or would receive it on a later age. Most people would receive their soul marks before the age of five.

Flower drawings, animals, words, sentences really anything you could possibly imagine. Everyone however would have to at least carry one word. Something to identify their mates with and sometimes this mark would give miracles. Some would have to wait for years to be finally completed with one other person in the big world they lived in and others found each other within seconds. It was a torturous process to wait for the one person, it had always been and always will be.

These soulmates would be your anchor to this world and your other half, your significant other who you just couldn't live without with. Hearing about the actual significance of a soulmate, every child would start wondering where theirs were. Always looking for them whenever they could, waiting for a sign to come to them even if only subconsciously.

''Congratulations, Miss Katsuki! A healthy baby boy, what are you going to name him?'' the doctors put a just cleaned baby on Hiroko's chest and it seemed that the baby felt at ease within a mere seconds and the mother had fallen in love once again with the tiny life that was lying on her chest. ''Hello there Yuri.'' Hiroko coed the baby and gently caressed his little head with her fingers. ''Your name will be written with the characters 勇利 like courage. A beautiful name for a beautiful baby boy.'' Hiroko sighed in satisfaction as she held this tiny precious life close to her never wanting to let go of him already.

Katsuki Yuri had been born a healthy child, weight average and all senses perfectly intact as far as the doctors could see. The entire family had been esthetic with the arrival of their newest family member and immediately began doting on him. Even as a sister Mari had become attached to the little bundle of joy.

Daily doses of pleasure and happiness were a natural given within the family after having another member added to them.

Sounds of laughter always filled their warm house and of course little Yuri himself loved to play with his big sister and parents. It was one happy family.

But everything was going to get turned upside down after little five year old Mari came running into the kitchen in tears.

''Mommy! Mommy! Something is wrong with Yuu-kun! He won't stop crying!'' Mari ran to her mother in a panicked frenzy as she began tugging at her mother's apron like crazy. ''Mommy!'' She pulled at Hiroko at all her might who looked at her child in worry.

''What is it Mari? Calm down first.'' Mari began to cry as she and Hiroko hurried to the living room where they could hear Yuri crying too. Yuri had been around two months old, but his crying was abnormal. Surely his lungs weren't all that strong yet as a baby, but even Hiroko would notice how he would cry and glance around the room with glazed eyes. His cries sounded pained and the moment Hiroko put her hand on his head she gasped.

''Toshiya! Hurry get the car!'' everything from then on became a blur to the little family of four, at that moment three. Hiroko and Toshiya's baby had been taken by some nurses after finding out how high Yuri's fever actually was.

Mari had stopped crying, but Hiroko kept leaning onto her husband the entire time that they waited for news about their baby.

After two hours luckily a doctor appeared in the waiting room making several people shot up from within their chairs. But to their disappointment it had been the Katsuki family and not theirs, the Katsuki family pitied the other families waiting in the emergency room, but couldn't wait to hear about their youngest family member.

'' Well, your son's fever has gone down quite a bit already. But in any cases, fevers aren't favorable with children, as you might know, not when their bodies are still weak and vulnerable. We might need to keep him here at the hospital for extra observation since it was quite the fever he had.'' At that time both Hiroko and her little family had been relieved to hear that he was alright, but making him stay at the hospital on his own?

In the end it was decided Katsuki Yuri was to be put up for extra observation in hospital where either Hiroko or Toshiya would stay every night with him.

Forcing him to stay for months in the hospital. They found out that Yuri's muscles were underdeveloped and there was no hope for his condition improving much in his entire life to come according to some doctors, but the parents kept strong and held hope. Yuri still had lots to see and they weren't going to let his weak body stop him.

It was only later that the doctors found out that they entirely misjudged the situation and gave him a wrong prognosis. Hiroko and her husband had held onto that little bit of hope for their baby boy's recovery, however everything turned around in a whirling mess and devastation hit them both hard.

''I'm sorry, but your son has- , it seemed like we underestimated the situation of his fever and all the other symptoms. I can't apology for what a failure as a doctor I am.'' The married couple stood there next to each other with a mumbling Yuri in his little crib which was surrounded by many tubes and machines left and right.

''What are we going to do Toshiya?'' Hiroko looked at her husband, both deprived of probably any sleep these days. ''I really don't know, honey.'' They turned their eyes to look at their little boy who had been playing in delight with his older sister, both were giggling even if Yuri had been attached to some IV drips.

Yuri had been one-year-old exactly, but had never really seen the world outside. It pained the parents to a great extent and were ridden with guilt as they stared at their child surrounded with machines all around him making noises here and there.

''Yuu-kun? What is that on your belly?'' Yuri slapped on his belly in delight as he obviously didn't understand his sister's words yet.

Toshiya turned to Hiroko and they both leapt to their son and pulled up his shirt. ''Oh my goodness…'' Hiroko began tearing up and looked at her husband who held her hand tightly.

''Hiroko, I've come to the conclusion. We need to stay strong for Yuri, after all there is someone else who might need him here.'' He looked at the strangle letters on Yuri's hip and slightly touched it.

They were proud, their little Yuri had been blessed with the most beautiful pattern on his body that they had ever seen in the hospital Yuri and his mother stayed at.

A beautiful teal-ish blue that would lightly shine, colors and streaks over his hip and slightly reaching his belly. The thought of that picture being completed made the parents simply happy, because they now knew that great adventures were waiting on their son until he met his soulmate at least. But that had only been half of the entire picture of course. They would never be able to guess what was awaiting them at that moment.

Come at me with those pitchforks I'm ready (actually lying and sweating in angst...)

Don't ask me why I decided to write this, I'm just an angsty teenager writing some angst obviously haha... Anyways~ Please follow or comment or whatever~
