The instruction manual appeared on Park Soo-jin's desk without any explanation. A leather-bound book, antique in appearance, with a single word embossed on its cover: "REGRESSOR."

He found it during his morning coffee, right where his scattered papers had been minutes before. The room's security system showed no intrusion. The lock on his apartment door remained secure. It was as if the book had been there all along, waiting for him to notice.

Against his better judgment, Soo-jin opened it.

The text was written in Korean, but with an organizational structure that suggested translation from another language. Chapters described regression mechanics, temporal loops, paradox avoidance, and most critically—the cost and mechanics of reversing time.

But what caught Soo-jin's attention was chapter three: a detailed listing of major historical events and their outcomes, written as if from future knowledge. Wars and their resolutions, technological breakthroughs, political collapses—all described with specificity that went far beyond reasonable guessing.

And interspersed within these predictions were warnings: observations about which events were fixed points (unchangeable regardless of intervention) and which were probability nodes (outcomes that could be shifted through careful manipulation).

The manual's introduction stated clearly:

*"You have been selected as a Regressor. Your task is to navigate temporal loops, gather information about the future, and prevent catastrophic outcomes that would otherwise occur. Success requires three things: knowledge of future events (provided in this manual), willingness to sacrifice present relationships for future salvation, and absolute commitment to established protocols."*

Soo-jin spent three days reading and rereading the manual, convincing himself it was an elaborate hoax. Some kind of very detailed fiction or elaborate roleplay game. The alternative—that time regression was real and he'd been chosen to participate—was too impossible to accept.

But then the first prediction in the manual proved accurate.

A stock market crash that the financial news had predicted would be moderate instead became catastrophic. Exactly as the manual had described. Exactly as the manual said it would if Soo-jin intervened by "selling shares in Company X before Tuesday's announcement."

Which he had done, following the manual's instruction. Without that instruction, he'd have lost everything in the crash like millions of others.

The realization hit him like acceleration: the manual wasn't hypothetical. It was operational. It was describing an actual future, one that had somehow been documented and placed in his past to guide his actions.

Subsequent chapters outlined his role: "Prevent the convergence event of 2047." "Safeguard the genetic research that would otherwise be destroyed in corporate warfare." "Ensure that Dr. Park Min-jung survives to complete her research."

The implications were staggering. A future so catastrophic that interdimensional operatives had apparently established a project to alter its course through carefully placed individuals and instruction manuals.

As Soo-jin progressed through the manual, taking each recommended action, each guided decision, he began to notice a pattern. The manual was moving him toward specific locations, introducing him to specific people, guiding him toward situations where he would either prevent disaster or accelerate it depending on his choices.

And the stakes were becoming increasingly clear. Each action he took had butterfly-effect ramifications. Each choice closed off alternative futures. He was no longer just an ordinary analyst—he was becoming an active force in temporal mechanics, a Regressor whose decisions would ripple across decades.

On what should have been an ordinary Tuesday, Soo-jin received a message on his phone:

*"Initiate contact with Dr. Park Min-jung. Prevent her assassination scheduled for tomorrow at 3:47 PM. The manual contains her location and your tactical route. Failure results in timeline collapse."*

The manual's final pages contained contingencies, exit strategies, information about how to recognize other Regressors, and most disturbingly—a list of historical events that "must not be changed" regardless of human cost.

Soo-jin understood then that the manual's purpose wasn't to save humanity. It was to optimize a specific timeline outcome, and some suffering was deemed acceptable in achieving that optimization.

The question that would define everything ahead was simple: could he follow the manual's guidance while maintaining his own moral compass? Or would pursuing a predetermined future require sacrificing every ethical principle he'd retained?

As he left his apartment to prevent Dr. Park's assassination, Soo-jin realized he was no longer in control of his own fate. The Regressor Instruction Manual had taken that from him.

The only question remaining was whether it had given him something worthwhile in exchange.
