The Only Reason

[Yandere!Sung Jinwoo x Worker!Reader]

Note: I have no idea what to call this AU, but I don't think a lot of people will read this so... Haha~ Mental AU? Chaos AU?

Update! This AU is called Mana Chaos AU! Plus there's Part 2 up!!

Part 1 (here) 一 Part 2

Once, the world’s strongest Hunters were revered as humanity’s saviours and heroes for the weak and ordinary. They were once treated like celebrities and hold the highest power and authority. They were respected, praised, and idolized. They still were, now, with a hint of fear.

It all happened due to the infamous incident now dubbed as <The Outrage Incident>. It happened like any other day, in any other country, in any other city. But to only that one strong Hunter. He was an S-Rank Mage, a successful and loved one at that. The story goes like this.

One day, this powerful Hunter was out on the street enjoying a day off, but something set him off and he used his powerful ability to set things right. It would have been the end of it since an S-Rank’s threat was enough to make the majority crumble. However, his power got out of control and caused an outrage to his being. He was using his powers in public and there was no dungeon outbreak or monsters nearby for him. No amount of justification could calm the public.

After that one incident, other countries’ S-Rank or higher started to experience a similar issue. The worst case was that even Healers of their level didn’t escape such a phenomenon. Soon, the public feared the strong protectors they once saw as shields and swords against the gates.

Researchers and scientists were put to work quickly to investigate why and how this issue was happening now. The answer was in the overflowing mana levels within their bodies that couldn’t be contained since the human body was weak and frail for such a change. Addition to that, it correlated to the Hunter’s emotional level and their control. Institutions were built to imprison house the S-Ranks while monitoring their situation.

Whenever an S-Rank’s mana levels and emotions show signs of <Outrage>, a term they now use to describe the Hunter going haywire with their powers on everything and anything around them, they will be sent to a dungeon alone. In the people’s eyes, it was better for that one Hunter to die in battle than kill innocents. Because at first, it was only the S-Ranks, but then some A-Ranks would fall victim to <Outrage> as well.

The professionals have named the correlation as Emotional Mana, EM for short, which made way for the Emotional Mana Institution, EMI for strong Hunters. The Hunters were treated like mental patients or worse, forced into a straitjacket and some had a muzzle for certain Hunters. These were specially designed and created items that limit and restricts a Hunter’s use of their powers and abilities.

It was a miracle that someone managed to create such equipment. That someone was also targetted by the S-Ranks after being announced and killed for such a disrespectful act, still the blueprints and prototypes were created and other talents that took over were able to finalize the perfect form.

“Personnel 002, you were specifically requested by SM-10.”

You looked up from your laptop and paused in your rapid typing for just a few second before you looked back to your screen and continued typing. That code name was to protect you and everyone else that worked in EMI or have some form of connection to it, so that no innocent is sacrificed for the greater good. Still, you can’t get used to it nor do you want to. “I’m busy.”

“Please… SM-10 is way too picky with the people that enters his cell.” This person, Supervisor 843, was one of the newest employee to join the crew. Though, unlike the name of the duty, they were people that were disposable hence the frequent newcomers and high number. “Please help me.”

You sighed and glared up at the person who had a mask over their head and a voice changer to mask their identity. Though, with the way they were speaking, you could deduce this person was a ‘she’. You got up and snatched the file extended to you. Just when you thought you could rest and work in peace, trouble comes knocking on your door. “Get me a drink and some refreshment, I want to see it on my desk by the time I’m back.”

“Yes? Yes!” Supervisor 843 bowed and clapped her hands together, “I’ll do so!”

As swiftly and automatically, you made your way through the hallways and doorways, tapping your access card to unlock needed doors and lifts for your travel. On the way, other Supervisors nodded their heads and bowed in your presence when you walked by. Unlike them who wear a uniform, you only have a lab coat over your usual outfits. You don’t even have a mask or voice changer.

Why?

You stood in front of the door that was labelled in bold ‘SM-10’, meaning the 10th S-Rank in Korea that belonged to the Mage class. The guard dressed in black from head to toe nodded their heads at you before they started unlocking the various security checkpoints and locks for you to enter into a battlefield in its own right.

“Will one hour be enough, Personnel 002?” One of the guards asked.

“Not sure, just be alert in case I need to rush out.” You spoke stoically with indifference.

Step by step, you walked in, announcing loudly of your arrival to the individual inside. The doors closed behind you and locked you inside with what everyone feared. You sighed and put away your glasses since there was no need for it right now. The room was eerily silent and cold, something you were long used to.

You took a few more steps, walking deeper into the room where it seemed to get darker and darker even though the lights in all housed Hunters would be on 24/7 to monitor their actions and activities within the room.

Just when your vision failed you to the point where you can’t see what was in front of you, you were enveloped in a pair of strong arms, your entire form effortlessly pulled back till your back was pressed against a firm wall of muscle one would call chest and abs. Hair tickled one side of your cheek and neck, you felt a breath cooed before a deep voice rang in your ear, “I’ve been waiting for my favourite Personnel~”

It wasn’t at all odd that your name was called as well, if it was someone like him, he’d know everything there was to know. In fact, everyone should be worshipping him right now for his controlled and well-mannered behaviour. Especially when he could have destroyed this entire facility and killed everyone in it within seconds if he so wished.

“Jinwoo. I need to work, don’t bully the newcomers.” You sighed while looking to the side as if making eye contact with him.

“I like it when you call me by name and not some code, thanks for that.” Jinwoo hummed as he played with your fingers. “I guess I’ll think about it. It’s a bit bored here, you understand.”

“You removed your straitjacket again.” You let him fiddle with your fingers as if it was the most interesting thing in the world. “You’ll get caught one of these days and then it’ll be game over.”

“Igris helped me remove it. You know how they are with seeing me constrained and imprisoned here.” He chuckled and leaned back, but it turned out he was just taking a seat, presumably on his bed since you still couldn’t see anything in the darkness. “Don’t worry, I’ve made sure no one could see me free and they didn’t kill anyone. Yet.”

Every Hunter that was admitted into the EMI was evaluated and thoroughly investigated to create the perfect profile for reference. All their fighting style, powers and abilities, weapons of choice, gear type, and any other detail was accounted down. It was all for people to be prepared in case one would have an <Outrage> and they were needed to be countered by weaker Hunters.

For Jinwoo, however, his profile was lacking to put it in the best terms. His mana levels were unmeasureable, yes, so he was placed as an S-Rank. Though, his powers and abilities were unknown. Since he was a Reawakened Hunter, most would assume he was the same class as he was as an E-Rank; a Fighter Class. But he exhibit <Telekinese> and <Shadow Manipulation> so he was placed as into Mage class.

That wasn’t even the tip of the iceberg.

You saw through his innocence and lie, uncovering his true powers and abilities. To be honest, even if you told your higher-ups of Jinwoo’s secrets, there was nothing they could do to counter it. Jinwoo was a league of his own and only you knew it. He was no mere S-Rank, he was definitely a National Level Hunter.

Ah, yes. The question as to why you don’t wear a mask or bother having done anything to hide your identity. It was not because you’ve been in one of the people who has been in service of EMI for the longest time or wanted something as shallow as respect from the newcomers or other coworkers. It was completely because you knew it was useless to hide when someone like Sung Jinwoo had his eyes on you.

“I’ll try and arrange a dungeon for you to raid.” You marked down on your phone while Jinwoo continued to treat you like a teddy bear.

“You have to join though. If you don’t…” Jinwoo’s voice went deeper as glowing eyes stared at you from the shadows, “I don’t know what I’ll do to get your attention…”

You nodded, pushing down the urge to flinch or jerk away from him. It was normal, something you expected but still unnerving to hear with your own ear from his lips. You swear this place made the Hunters mad in the head, it was a place that made them sick and mentally ill, it wasn’t actually helping them at all. “Yeah, of course. I’m sure everyone will be relieved to hear it.”

Jinwoo smirked as his arms tightened around you, his face buried between your neck and shoulder. “You’re the only reason I stay here. Remember that. If you leave here… Leave me… I’ll do what Thomas Andre did to America.”

Note: I can't help it, it was supposed to upload the requested ones first, but then this idea hit me like a truck (without the isekai part), so now here it is. There are like 2 requested stories written and ready to be posted, but I'm double checking and stuff. Hope you like this AU/idea.

The Only Reason _ Part 3

[Yandere!Sung Jinwoo x Worker!Reader - Mana Chaos AU]

Part 1 — Part 2 — Part 3 (here)

“Sung Jinwoo is an S-Rank Hunter…”

“Another one…”

“It’s been 2 years since Cha Hae-In too.”

Nowadays, the emergence of an S-Rank Hunter and some A-Rank Hunters was like a demon had crawled out of hell and into the human world to cause destruction. Strong Hunters were seen and painted as a double-edged sword. On one hand, they could bring about peace to normal—non-awakened—individuals by closing gates and raiding dungeons. On the other hand, they could bring about destruction in their wake due to <Outrage> and the innocence would be harmed.

Protocols like an awakened Hunter must report to the EMI instead of the Hunter Association because they have to keep track of stronger Hunters. Hunters must continuously measure their mana levels in case of a reawakening into a higher rank. It was unavoidable, no matter which country, because they prioritized ordinary people more.

Perhaps the only place where EMI regulations can’t touch is America. After what Thomas Andre had done, he singlehandedly protected his fellow Hunters and announced to the EMI that they couldn’t have their way with people who worked to protect them from the dangers known as gates and dungeons. There were some Hunters that escaped to America to join Thomas and his stance, there were also some that were unluckily caught by the EMI, and some that didn’t do anything. Such is the sway of a National Level Hunter.

Unlike Thomas, who had no weaknesses to use against, Jinwoo was different. His family, his mother and younger sister, were dependent on the society and their system. So, against his better judgement, Jinwoo bowed to the whims of the EMI and was taken in as SM-10.

In the facility, he underwent several tests to draw a profile for him since he was fundamentally different from his E-Rank file. Anyone could see at a glance. Jinwoo kept his cards hidden because the more capable he was, the greater the danger his loved ones would be in. He was doing everything for his family. Upon capture, he was promised that his family would receive financial support so long as he behaved himself.

A cowardly but effective threat and compromise that he agreed.

Still, he hated the people who worked in this accursed building. All those labourers who hid behind a mask and voice changer donned uniforms that displayed their station. Throughout his days, he observed a few groups of workers.

First was the type that he frequently came into contact with: Guard. As their station name, they guarded things, from equipment to rooms and even Hunter cells. They were the ones that handled conflict and violence, even the heavy lifting, if any. Those who were higher ranked were called Warden; however, he only saw them during his testing sessions when they were making his profile. They all wear black masks—Warden’s mask is black with a white scratch mark over the right eyehole—and black soldier uniforms.

Second was the type that constantly changes to the point he doesn’t even keep track of: Supervisor. Contrary to their high-standing title, they do the smallest and most insignificant tasks, like delivering supplies, checking Hunter cells, and being an owl so passing messages. They were low-ranking workers that most wouldn’t bat an eye to if gone. Perhaps that’s why they have a grey uniform and a grey mask. Their code went as high as the hundreds, going to the thousands.

Third was the type that he hated most: Investigator or Researcher. They were the ones who administered the tests and punishments to the Hunters, and they monitored them inside their cell. Under their glances, a Hunter is reduced to a mere lab rat. They were individuals connected to the EMI but needed to be more important to make a—any—difference in the building. However, they were respected in some sense because some did aim for the betterment of the Hunters staying in the building. They wear a white mask with a mocking grin and a white uniform, complete with a lab coat.

Last was the type that intrigued him the most: Personnel. Though their code suggests they have people in the hundreds, there was actually only a handful of them in the building. The highest number he saw was 12. They were the ones with the most authority and well-respected individuals among the other groups, their work and station varied from individual to individual. They were the ones that stayed in the building the longest, and a new Personnel would only join their ranks if they carried confidential information about the EMI.

One would notice there doesn’t seem to be a highest position or individual, but the Personnel were the ones who acted as the say of the facility. None had absolute power to keep each other in check, and in case a threat was targeted, if one fell, the other would continue in the other’s place. The smaller the number, the bigger their authority, it seems.

Personnel 001 was once his observer during the tests, when he could let loose. After all the observation and boredom, Jinwoo accidentally killed them and was quickly restrained. He paid close attention to what happened. Would another observe him? Would there be a new Personnel in their ranks? What would happen?

Turns out, you happened.

Personnel’s clothing is ever-changing. They have free reign over what they want to wear; needless to say, they have no uniform. They only have to wear a lab coat over their usual outfits, and that’s it. One could mistake them for Investigators, but the distinct code would be shown on their coat at the area over their heart. They have a white mask with reflective black glasses covering their eyeholes.

Yet when you came in, you were void of that mask that hides one’s expression and face. Still, your poker face was impressive. You appeared expressionless and reminded him of a doll. You neither introduced yourself nor showcased your station, different from Personnel 001, who was practically shouting at him that they were the ones in power in this facility. At first glance, he knew you were different from all the rest.

“You’re hiding your cards. SM-10.” Your words held knowledge and confidence, stating a fact rather than questioning him. Your arm hugged a black clipboard with a small stack of papers clipped while your other hand held a pen. If you weren’t wearing a lab coat, you’d appear like a strict teacher or lab researcher.

He couldn’t help but let a smile spread over his lips, “What makes you think that?”

“You’re holding back.” You turned to the Guards stationed within the cell to leave you alone. Yes, a Personnel has the authority to be alone with a Hunter, but if it were a Supervisor, they must be with at least two to three Guards. “You killed Personnel 001, why? Be honest.”

There was a shine in your eyes that he noticed. He couldn’t tell what it was, though he wanted to be coy. “You’re not the only ones observing. Why not make it mutual?”

That was his first meeting with you.

With his Shadows, he watched you and your daily activities. You were practically glued to your work; you came to work early but left late. You have a good relationship with the other coworkers, and most respect you, evident by the nodding heads you receive in the hallways. You also seem to care for Hunters in their cells, inspecting the cell quality and making things more bearable for Hunters like him.

Thanks to him, more and better changes happened after Personnel 001 was removed. By then, he figured out that whether it was a company setting or a guild setting, 001 was the guild master, and you were the vice master. Once 001 was gone, you had more authority and implemented changes, of course, with the agreement of your other Personnel co-workers.

In that case, that makes you a lot more interesting. You realized his strength and power, you wanted an improved and more sophisticated place for Hunter, different from how the facility was supposed to be, and you have been treating everyone human.

Jinwoo concluded that he wanted to stay and get closer to you. With you in charge, his family was practically safe as well. He’ll stay and protect your spot at the top. Yet why were you pushing him away? It infuriated him. Still, he was thankful for the other Personnels’ fear over setting an S-Rank loose in public that he could prove to you how wrong you were to fight for his release.

While showing his point, he reduced the Personnel to perhaps 6 remaining—that already includes you. From 12 to 6, he cut off 4, and then there was 001 as well, so one Personnel died through other means. Either way, he made his point.

You were the only Personnel he liked and could resolve his <Outrage>.

That already bound you to him, and none would harm you unless they wanted the country to fall to ruins.

The two of you share secrets, and slowly, he got you to open up, showing only him a side of you that you hide behind an invisible mask. You’re the only one for him, he’ll make it so that he’s the only one for you.

He realized that his emotions and feelings for you turned a bit twisted over time. That Guard 149 that stared at you a little too long? Their leg was somehow caught between the double doors, so they can’t work here anymore, right? That Investigator 083 that was standing so close to you that your arms were touching? An experiment backfired and their arms were amputated. Another Guard that is coded 761 was asking you out? They got into a car accident and died.

Jinwoo was careful. You never pointed fingers at him nor suspected it was him at all. You were very naive and innocent; he loves that about you. You care for your workers, yet at the same time, you also don’t. He got his answer when he finally communicated with the other S-Rank Hunters during the end of the Jeju Raid.

“Personnel 002? Oh, I’d say that person cares about Hunters more.”

“Haha, Personnel 002 has been very accommodating, unlike the other ones.”

“You can’t compare Personnel 002 with the others, it’s not a fair comparison.”

“I always enjoy my time with Personnel 002.”

“You’re lucky SM-10, I wish I could have Personnel 002 come to my place often.”

The other S-Rank Hunters only had good things to say about you. As expected, you were biased against Hunters and silently helped them more. Though, he was more enraptured to hear you giving him special care and attention. In private, his smile grew wide as he chuckled to himself. “Ah… You’ll be the death of me… Personnel 002.”

Note: Ta da! Part 3's out and this is Jinwoo's side of the story, if it wasn't obvious to you!! A bit of boring history, but it's what it is~ Hope you guys liked this one!
