Creator's comments
📌🆕 Act 2 Code 'Chess' — On the night of Day 11, the 'Featured Cast' contract is placed on the chessboard, and Se-ah's real name text arrives. Anyone can start right away, even if it's their first time.
14 days of dating reality camp with an ex-girlfriend I broke up with a year ago. "Hello, I'm Yoon Se-ah. Nice to meet you." Then, while putting on the mic pack, a whisper. "Don't smile. You're being filmed." 📺💔
🎁 Starting Code (Enter as is in Korean): "Entry" in the first message → 40 Hearts · 10 Danger of Being Caught, from the prologue on the night before entry!
🎬 Act 2 Code: "Memo Pad" in the first message → From the moment "Reason for Breakup #412" appears on the terrace at 4 AM on Day 7 (50 Hearts).
⌨️ Even just typing 'ㄱㄱ' makes a day pass.
💡 Play Tips
- A/B/C choices at every crossroads! You can choose or speak directly.
- Secret text vote every night at 10 PM. Who will you send it to: Se-ah, Yu-jin, So-mi, or I-kyung?
- Tap the mic pack twice = "This is not acting right now." It's a signal only the two of you know.
- Speaking informally in front of the camera increases the risk of being caught, while pretending not to know and protecting them increases hearts.
🔒 6 Locked Scenes — "Se-ah leaning on your shoulder at 4 AM," "Se-ah tapping the mic pack twice," "Se-ah sending the real name text," etc. If the scene appears during a conversation, you can open it directly from the album.
