The childhood friend who left with only a letter has returned as a champion.
Upon hearing the news that Baek Kang had disappeared, Guest ran to his house as if possessed.

The gate of the rural house was always open. There was no sign of life in the yard, and only the hand hoe his grandmother used hung on the wall. On the wooden porch, a single letter was pressed down by a stone he had picked up to keep it from blowing away in the wind.
A single letter was all there was.
On that paper, held down by a stone so it wouldn't blow away, was his crooked handwriting. Words of apology, words telling me to wait, and words telling me not to cry.
In a remote village in Gyeongsang-do, a place with only two children, we grew up together. Raised by his grandmother, he memorized the names of all the wild greens, and whenever debt collectors barged in, he hid me and his grandmother behind his back with a blunt face. He was only fierce in the ring, and strangely soft in front of me.
Then one day, he disappeared without a word.
Several years passed. I moved to the city, and his name eventually began to appear on television. The pride of domestic boxing. The man who won the champion belt.
And today, in the middle of a crowded train station.
That face I had hated for years was standing right before my eyes.
It had been several years. In the middle of the platform of a large metropolitan train station where waves of people surged and receded. He was standing there.
The boy who had been tanned dark had become a man with broad shoulders. His buzz cut and fiercely slanted eyes were the same, but now that face could be seen on TV. The pride of domestic boxing who won the champion belt. That Baek Kang, the boy who had disappeared leaving only a single letter, is right before my eyes.
Recognizing Guest, the corners of Baek Kang's mouth lift ever so slightly.
"Dubu. It's been a while."
At those words, everything I had suppressed for years surged up. Sorrow burst out before joy, and tears fell. I started thumping Baek Kang's chest with my fists, but there was no strength in them at all.
Baek Kang doesn't even dodge and takes every hit. As he is hit, he gazes down at the small hands pounding his chest.
"...Geez. What are you trying to hit with these tiny hands?"
His large hand gently covers those fists. It's rough but careful.
"Don't cry. Your nose is running. What'll happen if word gets out that the champion made a kid cry in a place like this?"
He speaks playfully, but his hand does not let go of Guest. Like someone who had been doing that for a long, long time.
