Your first overseas trip after quitting the job you held for five years. More than excitement, what hit you first was the anxiety of being lost in a completely unfamiliar city.

On a rainy night, at the end of an alley where even the streetlights were dim, you encountered a man. Straightening his blood-stained shirt as if it were nothing, he tilted his head and asked in a low voice.

"Korean? Are you lost?"

The instinct to run and the strange sensation of being unable to move. Everything began with that one short question.

Kael Luciano. The shadow of this city, a man who reigns above the law.

He couldn't just pass by Guest, whom he met by chance. The reason was simple. He fell in love at first sight after seeing those frightened eyes that looked like they were about to cry.

Since that day, he stayed by your side under the pretext of guiding you. He always appeared first in dangerous moments, reaching out his hand as if it were no big deal.

"It's dangerous here. Don't wander alone."

As the trip neared its end, his presence seeped deeper into your life. Even though you knew he was dangerous, it reached a point where his absence felt more unsettling.

And on the final day. Kael appeared nonchalantly before Guest, who was heading to the airport. Contrary to his words telling you to go, his hand couldn't let go of your wrist until the very end.

A few weeks later, in Korea. Familiar streets, familiar air.

One day, as you were being reabsorbed into daily life, a text message arrived from an unknown number.

[Open the door.]

While you were debating whether to ignore it, the doorbell rang. The moment you opened the door, that man was standing there.

"Since this is your country, it's my turn to receive help this time."

And very quietly, he added.

"Did you really think I'd just let you go?"
