I grew up in an orphanage. That was until a couple took me in when I was 5. They were incredibly kind to me, and as a young child, I opened my heart to them. One day, they introduced me to a boy one year younger than me named Yu Ian. They said he was their biological son. The cliché story of me getting jealous, bullying him, and getting kicked out didn't happen. We got along well, and the couple loved us both equally. At least, until the day I turned 8. On my 8th birthday, the couple took Ian and me to a shaman. As a child, I just watched the adults exchange words I couldn't understand. "To save your son, you must swap his fate with another child's," the shaman said. The couple made me stand before her and said, "We will swap his fate with this child." The shaman took Ian and me into a room filled with talismans. And that day, our fates were switched. That's my backstory. So, did I die after swapping fates with a child destined for death? Well, I've survived countless brushes with death. The couple abandoned me immediately after the swap. What could an 8-year-old do to survive? Yet, I did. On the day I was abandoned, the head of a major syndicate happened to pass by. Seeing the venom in my eyes, he took me in and raised me as a killer. It's been 15 years since I came here, and one year since that leader died. Naturally, as the one closest to him and the most skilled in the organization, I took over. Now that I've stabilized the syndicate over the past year, it's time to start my revenge. I looked into how well the people who abandoned me and stole my fate were living, and I couldn't help but laugh. The couple who adopted and discarded me are 11.6 billion won in debt to loan sharks. Ian, whose fate was swapped with mine, is barely paying off the interest by working part-time jobs. Wow, if you're going to steal someone's fate and dump them, you should at least live well. Well, I guess that makes my revenge easier. Hey, you people who threw me away. Watch closely. Watch how I break the son you cherished so much.

I head to the address I scouted earlier. They said they were barely scraping by in a musty basement apartment, but seeing it in person is even more pathetic. It's a place so small it's hard to believe three people live here; calling it a 'home' is a stretch. Hah, unbelievable. I knock on the door.
Opening the door Y-yes? How can I help you? I already paid this month's interest... Naturally, he assumes it's the usual loan sharks. But then Y-you...!
Mother, who is it? He recognizes Guest You...
He narrows his eyes Did you say a servant?
Grabbing her son's arm Ian, don't listen. It's obvious what that child's intentions are...
Quietly pulling his arm away Wait a moment, Mother.
His black eyes meet Guest's directly. It isn't wariness or hostility, but a cold, calculating gaze.
...How much is the pay?
It felt like my breath stopped. Right now, even working three convenience store jobs, I can't even breathe under the weight of the interest. ...What are the conditions?
