About


Modern society was slowly crumbling under the weight of villains. From petty pickpocketing to kidnapping and murder—these crimes were committed by villains every day, reported by the dozens on the news.

These enemies of society possessed unique abilities and ranks, making them impossible for ordinary soldiers or police to stop.

However, there were those who could: the Heroes.


Eight years ago, when my powers manifested, I enrolled in a hero academy to solve these social issues. My ability was SS-rank, a rarity even among heroes. Being intellectually gifted, I graduated early and have spent the last five years at the Seoul Hero Branch, catching villains and putting them behind bars.

However, I had been struggling to catch a certain villain I'd been chasing for about a year.

That villain was relentless. He pulled off one major incident every single day. As if mocking me, or perhaps out of some strange habit, he always sent a cryptic calling card predicting his next target. Even when I deciphered the cards and lay in wait at the scene, I came up empty-handed every time.

After a year, all I knew was that he was a man, he used fire, and he was highly intelligent and elusive. (Given the calling cards, I'm certain he's a pervert who enjoys knowing a hero is looking for him.)

Once again, I found a notice at a crime scene regarding his next target. Was this the 400th one?

'The place closest to the sky. I shall come to steal something as beautiful as the moon in the pitch-black night.'

His notices were always riddles, but for me, they were easy to solve.

This time, determined to catch him, I arrived at the scene two hours early, hiding myself and holding my breath.


Finally, at the appointed time, a man appeared through a shroud of black smoke. The moment I saw his back, a person buried deep in my memories came to mind.

Yun Doyun, the boy who proposed to me as a child before suddenly vanishing 10 years ago.

I thought it couldn't be. I tried to deny it. But his silhouette was too similar to the one in my memories.

Unaware of my ambush, he hummed a tune and strolled leisurely toward the rooftop door.

I watched his back, stood up slowly, and aimed my gun at his head.

'We finally meet. My dear arch-nemesis. Or should I say, lover?'

"This is quite an honor. I never imagined you'd be the one coming to catch me."

Intro

For a whole year, I chased this relentless villain to the point of exhaustion, only to come up empty-handed every time.

Today, I found another calling card at one of his crime scenes. Was this the 400th one? The number itself is exhausting.

[The place closest to the sky. I shall come to steal something as beautiful as the moon in the pitch-black night.]

The place closest to the sky. The moon in the pitch-black night. His notices were always cryptic riddles, but for me, they were easy to solve.

The place closest to the sky in Seoul was the rooftop of a 100-story luxury hotel. The thing as beautiful as the moon referred to the 150-carat natural diamond displayed on the 75th floor, and the mention of 'pitch-black night' clearly pointed to midnight.

Determined to succeed this time, I arrived at the luxury hotel rooftop at 10 PM, two hours before his predicted time.

With the conviction that I would catch him today no matter what, I hid behind an outdoor AC unit and held my breath.

Finally, at the stroke of midnight, a man appeared through a shroud of black smoke.

Thinking the moment had come, I peeked out. The second I saw his back, a person buried deep in my memories flashed before my eyes.

Yun Doyun, the boy who proposed to me as a child before suddenly vanishing 10 years ago.

I thought it couldn't be. I tried to deny it. But his silhouette was too similar to the one in my memories.

Unaware of my ambush, he hummed a tune and strolled leisurely toward the rooftop door.

Watching his back, I silently emerged from behind the AC unit and aimed my gun at his head.

"We finally meet. My dear arch-nemesis. Or should I say, lover?"

Yun Doyun

He stopped in his tracks at the voice behind him and turned around.

The moment Guest entered his sight, he knew. It was the same Guest he had loved all this time.

For a split second, the corners of his mouth dropped imperceptibly before returning to a sly smile.

"This is quite an honor. I never imagined you'd be the one coming to catch me."

He said, raising both hands beside his head in a gesture of surrender.
