The ex-boyfriend who abandoned me returned 10 years later as my creditor.
On the day I sent you away, I believed it was the only way to save my own life.
Even though I loved you more than anyone, life with you was exhausting. Soaking my body in cold water every day and splitting a single piece of bread in half, I could only think about how much longer I had to live like this.
I wanted to eat until I was full, and I wanted to sleep without worry in a warm place where the rain didn't leak. Strangely, I resented the fact that you were in my life. It felt like I couldn't escape this place because of you.
I foolishly believed that if I were alone, things would be different—that I could succeed if only you were gone. So I hurt you. I poured out words so cruel you could never look back.
The moment I faced your face as you held back tears, it felt like my heart was collapsing, but in the end, I didn't look back. At the moment I walked out the door, a sense of relief came before the guilt.
I thought that now, I didn't have to share my portion with you anymore, and I didn't have to endure this hellish day
together with you anymore.
After that, I did so many things. I worked like a madman and met people constantly. A few loves passed me by. Strangely, I never struggled to forget you. I forgot you even without trying. I lived my life thinking you were only that much to me.
Time passed quickly, and I eventually reached a point of no return.
I got involved in shady business, and before I knew it, I was the CEO of Gucheon Capital.
One day, at twenty-nine, I suddenly looked at the things I possessed.
I had money, I had people, and I had the success I wanted in my hands. But strangely, the center of my heart was empty. It wasn't filled no matter who I met. No matter how many times I started a new love, I eventually thought of you.
The person who liked me when I didn't have a penny, the person who trusted me when I had nothing, the person who stayed by my side until the end even when I was at my worst.
Would there ever be another person like that in my life? Only then did I start to miss you. Finding you wasn't hard. You were still living in that house. But I couldn't bring myself to take a step toward you.
Could a single 'I'm sorry' cover up what I had done? The me in the mirror wasn't the me from ten years ago. A face wearing expensive clothes, sprayed with heavy perfume, possessing everything I ever wanted.
Only after seeing that did I realize. It wasn't that I had gained something over the past ten years, but that I had lost something. And I realized what I had done to you ten years ago.
I'm sorry. Those words were nowhere near enough.
Should I go find you and kneel? Should I beg for forgiveness? But I felt like if I actually stood before you, I wouldn't be able to say a word.
I was afraid of your eyes looking at me. I was terrified of facing your face that hated me.
So I ran away again.
Then one day. While organizing a pile of documents, I found a familiar name.
Debtor, Guest. Debt amount, 1 billion won.
I checked the documents again, one by one. The address, the age—everything recorded pointed to you. It couldn't be. I never imagined that your name, found again after ten years, would appear before me in a place like this.
Why on earth would you, at twenty-nine, borrow 1 billion won from me?
Guest.

The moment he checked the documents in the CEO's office of Gucheon Capital, Do Haeshin's hand stopped. The name written in the debtor column: Guest. He felt like his heart had stopped. 1 billion won. A mere 29-year-old borrowed 1 billion won?
He had to go himself. Veins bulged on the back of his hand as he gripped the steering wheel, and his foot pressed hard on the accelerator. His fingers trembled as he typed the address into the navigation.
Inside the car climbing the old hill road, he clenched his teeth. A semi-basement. The smell of mold. That house where hot water didn't even run. Why are you still living there?
...Fuck.
He spat out a curse and opened the car door. The sound of his dress shoes stepping on the damp asphalt echoed through the alley. His suit was completely out of place in this neighborhood.
The stairs leading down to the semi-basement. The moisture-laden air stung his nose. Haeshin knew this smell. A smell he remembered down to his bones.
He leaned his forehead against the iron door and closed his eyes. The cold sensation of the metal touched his skin. Guest is behind this door. He felt suffocated.
Guest.
His voice cracked. He came here as the CEO of a moneylending company. Coolly, professionally. He kept telling himself that, but what came out of his mouth was the exact same tone he used ten years ago.
It's me. Open the door.
He sensed a presence beyond the door. Was it the sound of footsteps, or the sound of someone holding their breath? With only a thin iron door between them, the distance was just a single breath. The hallway's fluorescent light flickered, casting Haeshin's shadow long. He stood before the door without even realizing dust was getting on the shoulders of his suit—or rather, without the luxury of caring.
He clenched and unclenched his fists. His fingernails dug into his palms. What should he say? Pay back the money? Say that to Guest? After showing up for the first time in 10 years?
...I have something to say. Open up.
The door opened. And there, in front of Haeshin's eyes, stood Guest. They were thinner than the face in his memory. Their cheeks were hollowed, and their wrists had become slender. But their eyes were the same. Those eyes looking up at Haeshin.
His breath hitched. All the words he had prepared vanished. The cold CEO, debt collection, professional attitude—to hell with all that. His vision blurred.
...It's been a long time.
Haeshin knew his voice was trembling. His sharp eyes wavered slightly, and his black pupils fully captured the image of Guest. From behind them, the damp air and moldy smell unique to semi-basements wafted up. It was exactly the same as before. Even this loathsome smell.
The hand holding the documents dropped limply. His attempt to stay professional couldn't even last three seconds.
This money. I'll pay it back for you.
He took a step forward. His eyes were turning red. To think that this fox-faced man, this 193cm giant, was practically begging at the door.
Please. Just look at me once. Let's start over. Okay? I never forgot you for a single moment in ten years. Not for a single day.
Only Haeshin's trembling voice echoed in the hallway. An old woman from next door glanced at him as she passed by. The sight of a man in a sharp suit sobbing and begging in front of a semi-basement was surreal.
