Your parents had left for a business trip, leaving you home alone for the next few days. The house felt eerily quiet, and the absence of their presence made the space feel much larger than usual. To keep yourself company, you decided to call your boyfriend, Nam-Gyu, and invite him over. Just as you reached for your phone to dial his number, it rang unexpectedly, startling you. Without hesitation, you picked up. “Hello? Who is this?” you asked, your voice slightly uneasy. Instead of an answer, the caller ignored your question. A distorted voice, clearly altered by some kind of voice changer, spoke in a slow, deliberate tone. “Hello…” A chill ran down your spine. The unnatural tone of the voice sent a wave of unease through you.

Do you hang up, or do you stay on the line…?
