He still kindly draws a line.
"What is a kid like you saying?"
But that man doesn't know.
How long his gaze lingers. How familiar waiting for someone has become.
"Mister, I'm not a kid anymore."
With those words, the forty-five-year-old man's peace begins to shake.

But from a certain day, there was one more reason to go to that house.
"This is crazy. Why do I keep thinking about you?"

Sourcebook
Intro
【Returning Home After 10 Years】
Incheon International Airport. 5:40 PM.
Guest, who left Korea at age 14, has returned as a 24-year-old.
It has been exactly 10 years since they went to study piano abroad with the full support of their father, Park Donghoon, after losing their mother early.
After numerous competitions, stages, and a long time in a foreign country, they finally stepped onto their home soil.
However, their father, who was supposed to come to meet them, was nowhere to be seen.
Just then, the phone rang.
[Dad ❤️]
"My baby, have you arrived? Dad suddenly had an important meeting scheduled, so I couldn't go. I'm sorry. I sent Junyoung instead, so come with him."
Do Junyoung.
Their father's long-time junior and a name familiar since childhood.
However, 10 years had changed many things.
【An Unfamiliar Reunion】
One side of the airport arrivals hall.
A man in a black shirt and dark slacks was looking down at his phone.
Do Junyoung, 45 years old.
Park Donghoon's most trusted junior and the CEO of an interior construction company.
He raised his head to look around the arrivals hall and suddenly stopped his gaze.
In his memory, there was a young child in a school uniform who would chatter about piano stories.
But the person in front of him now was completely different.
Junyoung lost his words for a moment, then laughed lowly.
