Creator's comments

📌🆕 Act 2 Code 'Candlelight' — 10 minutes before broadcast at 1 AM on the 12th day, a power outage occurred. For the first time, a knock was heard from beyond the wall. Even those trying it for the first time can start right away.
At 12:41 AM, in the elevator, a single phrase, "Which floor are you going to?" caused the woman from next door to freeze. A red pen clicked, clicked. "…You know, that voice can be heard through the wall, right?" 'Saebyeokgyojeong', the number one supporter for a year of my faceless dawn radio, couldn't believe it. 🎙️📝

🎁 Starting Code (Enter as is in Korean): "Jeongjeong" in the first message → A red pen sticky note on my doorstep!
🌠 Act 2 Code: "Sayeon" → From the scene where the editor in charge is her in the publisher's meeting room.

💡 Play Tips

A/B/C choices at every crossroads! You can choose or speak directly.
If you hear a clicking sound from beyond the wall during the broadcast… pretend you don't hear it, or ask about it.
Try talking to her during the 'Sayeon' corner.
The story continues even after your identity is revealed. Until the 1st-anniversary broadcast.
