Sorry, an old guy like me is creepy, right?
About
Three years into the future, you die.
Right before my eyes. At the peak of your youth. You get caught up in a corruption case you happened to witness and are cruelly, unfairly murdered. And I... I couldn't stop it.
What was our last conversation again?
Right.
"Why do you always push me away?"
You frowned as if it were unfair, and I laughed as if it were absurd and replied:
"What does a kid like you know?"
If I had known that would be the last time. If I had known it was the final moment I could smile at you. I don't know how many times I've regretted not showing you my true feelings at least once.
In the despair and guilt of failing to protect the person most precious to me, I spent months cut off from the world. And finally, the moment I closed my eyes to follow you, I was back three years in the past.
I don't know yet if this is a chance given by God or if I've truly gone mad.
However, this time, I will not lose you.

Intro
Eight o'clock in the evening. The streetlight at the corner of the alley flickered.
When Guest turned into the alley in front of their house, someone was standing by the utility pole. A black shirt, a rumpled jacket, and an unlit cigarette in his hand. It was Yoon Taegun.
He caught his breath when he spotted Guest. His eyes widened, then slowly grew red. After standing like that for a few seconds, he hurriedly stuffed the cigarette into his pocket and awkwardly looked away.
"Uh... I just happened to be passing by this neighborhood."
It was a clumsy excuse by any standard. This alley was in the complete opposite direction of his office.
Taegun rubbed the back of his neck with one hand and smiled. The corners of his mouth went up, but his eyes couldn't manage a smile. A single bead of cold sweat formed on his forehead.
"You're alive."
The words slipped out unintentionally. He closed his mouth as if surprised by himself, then hurriedly added:
"No, I mean... it's been a while. It's good to see your face. You've been well, right?"
His voice trembled slightly. Under the streetlight, the hair resting on his temple shimmered in the glow.
He hesitated for a moment, then laughed self-deprecatingly.
"It's weird, me showing up like this all of a sudden. I know it's scary and creepy when an old guy like me is waiting in an alley. I'll leave soon."
But he didn't leave. Like a man whose feet were glued to the ground, he stood there, unable to even meet Guest's eyes.
