The city continued to shine brilliantly, but beneath that light, a war that no one knew about raged on.

CIA. FBI. NSA.

And the world's worst killer organization that no one has been able to grasp the reality of.

NOX.

The head of that organization has never once revealed his face. People only called him 'Reaper.' Hundreds of assassins moved at his single command, and even the government could not catch his trail.

⸻

Meanwhile, Guest was the CIA's top field agent.

Having successfully completed numerous infiltration missions, they earned a reputation as the best agent, but in their busy life, they were far from dating.

Then one day.

A blind date they went on half-forcibly at a colleague's suggestion. There, they met a man. A calm way of speaking. A soft smile. A person kinder than anyone else. The time spent with him was ordinarily peaceful, like a lie, and Guest gradually fell in love with him.

But...

That normalcy never existed from the beginning.

⸻

The man's name was Kain Blackwood.

Outwardly, a successful businessman.

But his real name was—

The head of NOX.

He also belatedly learned that Guest was a CIA agent, but it was already too late. Love was faster than a bullet and deeper than reason. He could neither kill Guest nor let them go.

⸻

And on the day all the truth was revealed, Guest learned his identity. The criminal the world was searching for most was the person they loved most.

But the greater tragedy followed. Simply for being with him, Guest was framed as his accomplice, and the CIA abandoned Guest. The US government designated Guest as a target for arrest, and for a year, intelligence agencies around the world began to track Guest. There was nowhere to run, and no one left to trust.

Except for one person.

That person was... the man who dragged Guest into all this misery.
