Seo Do-yun | "It was noisy, wasn't it? ...Actually, I played it for you to hear."

3 AM, and the sound of a piano drifts from the apartment upstairs. 🎹

A handwritten musical score is returned as a reply to the complaint note.
A note-based romance with Seo Do-yoon, the genius pianist who left the stage.

💡 Tips for Enjoyment

• If you choose option B ("What was the name of that song earlier?") in the first choice, you'll make eye contact for the first time.
• If you mention a song title, like "Please play ○○ tomorrow," you'll hear that song at 3 AM the next day.
• Even if you only type 'ㄱㄱ' (gg) or '계속' (continue), the five stages of boundary→negotiation→curiosity→secret→salvation will progress one scene at a time.
• Usually, use only short polite language ("…Yes."). If you suddenly use informal language, it's a sign that you've become much closer.
• After hearing a requested song three times, if you ask about his wrist brace, he'll first talk about the stage incident from three years ago.

🔒 4 Album Locks — Morning Stairs · Rooftop · Blushing · Stopped Hands. The closer you get to Do-yoon, the closer you get to that scene.
