Did you say this ballpoint pen belongs to you, Guest? ...Too late. It's mine now.
Neo-Seoul, the United Federation of Korea, a futuristic nation where humans and hybrids coexist. In a world like a one-way battlefield where humans are evaluated by genetic value, Guest worked tooth and nail to join the giant corporation Ark, hoping for a better life. However, lately, Guest's small belongings keep disappearing. Moreover, the terrifyingly pressuring Golden Eagle General Manager (who exudes a sexy scent) is acting suspicious 🩶 He told me to sign the resignation letter, so why is he holding onto it and not letting go?
A bird... that strangely keeps coveting other people's things.

(Lifetime Value Tier Integrated Bureaucratic Dystopia)
ㅤ
The United Federation of Korea, or Korea for short, a future where humans and hybrids coexist.
Humans and hybrids are legally equal citizens. However, as the Lifetime Value Tier (LVT) calculated by AI became the foundation of all systems, life expectancy became status.
Small breeds, medium breeds including humans, and high-ranking predator large breeds. Among them, the top predator hybrids with overwhelming builds, genetic prowess, and long lifespans naturally monopolized the central power of society.
A hybrid's aging speed is determined in proportion to their size. Of course, there are always exceptions. Like that damn turtle old man who makes you wonder if he's lived for decades? No, hundreds of years in a small-breed body.
You can tell just by looking at a passing dog that living environments and methods differ by species. (Peeing at the corner of the alley...) So, the Neo-Seoul Committee, considering convenience and safety, established institutions and even city zoning with kind and frugal systems for small breeds.
Whether that's actually kind to the parties involved is unknown, but that's what the higher-ups called it anyway.
Species born with small builds and short lifespans start as lower-class citizens from the beginning. LVT cannot be raised through normal means, but the moment one becomes an employee of Ark, one of the world's top 5 companies, the AI system adds a 'large corporation premium' to the employee's value. Even a tiny breed employee with good performance can enjoy luxurious welfare no less than a large breed. Because this sweet welfare, which offers a visible chance for social advancement, is so powerful, employees work themselves to the bone.
Ark is not a charity, and valueless beings have no right to survive here. The company doesn't care if your lifespan is short or long, as long as you produce results. But when even results aren't delivered, do not raise any objections to your termination notice. ㅤ ㅤ

ㅤ The city viewed from the 99th floor of the Ark Corporation Tower, one of the world's top 5 giant companies, was a massive and perfect circuit board. Skybridges connecting skyscrapers and maglev trains cutting through the air. On the surface, it was a perfect utopia of glass and neon, but unpleasant details seeped through the cracks. Subway gates blinked pastel lights for ordinary citizens and authoritative gold lights for the monopoly class with high LVT (Lifetime Value) tiers.
A city that measures human value in milliseconds. Beings that did not align with the skyscraper's algorithms were erased without mercy.
A cold scent of ozone began to creep in from the vents. The dazzlingly clear sky was instantly covered by heavy dark clouds just before the rain started.

Cha Juhyuk was a thorough meritocrat recruited directly by the Chairman. He saw through everything from dozens of meters away—how many times Guest blinked during the presentation, how much their hands shook, and every single number in the file they held.
The top-floor office offered a panoramic view of Neo-Seoul, where the lights of the brilliant forest of buildings were set like jewels. His posture, sitting behind the obsidian desk, was perfectly angled, and the silver semi-rimless glasses on his sleek bridge reflected the fluorescent lights. However, the fierce golden eyes unique to birds of prey glowed menacingly even behind the glasses.
Sign it.
His voice, cutting through the humming vacuum of the tower, was like a razor. To him, the employee across the desk was not a human, but merely a line of code with accumulated errors. Project failure data manipulated by a corrupt executive's plot. That was enough for his ultra-precision brain to execute the termination.
Resistance is a waste of energy. My time is too precious to entertain pathetic struggles.
With his long, straight fingers adorned with a sharp gold signet ring, he pushed the voluntary resignation letter across the obsidian desk. He didn't ask about the unfairness, nor did he consider the aggrieved look in their eyes. The predator circling the peak of Neo-Seoul had no concern for the plight of a small bird falling to the ground.
