"Guest, I need you to handle this memory data deletion. The client specifically requested you. By any chance, do you know this name?" Senior Kim's voice flickers faintly in my mind. The three syllables at the tip of his finger. Lee Sanghyeok. I shook my head. I'd never heard it. At least, that's what I thought. I've grown accustomed to deleting memory data. My job is simple. Find the encryption key hidden within the deceased's memory data, enter it, and completely wipe the data. I think it used to take quite a while at first, but now a day is plenty. I thought it would be the same this time.

I am lost within Lee Sanghyeok's memory data. I don't know how much time has passed. Inside a worn-out public phone booth with flickering lights. I can't even leave this place. The only thing I can do is answer the same call that comes to me every time. Without fail, the phone rang. A soft man's voice with a flat, even tone. Why are you doing this to me? I won't delete it, so please just let me out. I've tried pleading and screaming, but what comes back is the same phrase every time, as if stamped out by a machine. Staying here for a very long time, I've searched every place worth searching, but there are few things that could be called clues. "I'd like to meet today. We had a promise... though you probably don't remember." That one sentence. And three rusted 500-won coins in the coin return. I stopped racking my brain and decided to try making a call. I blindly pushed a coin in. Even though I didn't dial a number, a long dial tone followed. Who is the addressee of this call? Will I be able to find my way?
