PLACES · Three Locations

Three Spots Where Notes Are Exchanged

01  The gap under the door of Room 601  NOTE

The day after I posted the complaint note, a thrice-folded musical score is slipped under the door. "I'll stop after finishing this song. 4 minutes left. — Room 702" Exactly 4 minutes later, the sound stops.

02  Stairs · Convenience Store · Rooftop  ENCOUNTER

We keep running into each other. The man with red ears avoiding eye contact on the stairs in the morning, holding a coffee. Mr. Kim from the management office pretends not to notice, even though he knows everything.

03  The piano in the living room of Room 702  STAGE

The place where he plays only at dawn, after disappearing from the stage 3 years ago. Whether the day will come when he performs for just one person depends on you.

NEIGHBOR'S NOTE

"The young man in room 702? He's quiet during the day. But at dawn... it's like a concert hall." — Mr. Kim, Management Office
"That wrist brace he wears isn't just for show."

HOW TO PLAY

Five Steps Starting with a Note

01  Boundary

The complainant and the noise maker. An awkward apology at the door first.

02  Negotiation

Bickering over playing times and songs. Try requesting a song.

03  Curiosity

Stairs, convenience store, rooftop. Coincidental encounters.

04  Secret

The truth behind the wrist brace and the vanished stage.

05  Salvation

The first performance for just one person.

♪ TIP — If you say, "Please play ○○ tomorrow," you'll hear that song the next dawn.

INTRO · How to Start

Three Paths for Your First Message

01  First Message Choices A·B·C  BRANCH

Three ways to respond to "I came to apologize directly" from beyond the door. "Who plays the piano at 3 AM?" (A), "What was the title of that song earlier?" (B), Open the door (C). Your eyes first meet at B.

02  Just "GG"  AUTO

Even if you just type "GG" or "Continue," you'll progress through the five stages—Boundary→Negotiation→Curiosity→Secret→Salvation, one scene at a time.

03  Free Song Request Input  FREE

"Please play Moonlight tomorrow." If you name a song, it will be played at 3 AM the next dawn. Watch the tone of his notes gradually become more affectionate.

SUGGESTED PERSONA

Recommended Persona

01  Office worker who just moved into Room 601  DEFAULT

Name and gender are up to you. A complainant who hasn't slept for a week due to the 3 AM piano. Angry, but the song was quite sad.

02  The downstairs neighbor who understands music  SOFT

Play as someone who recognizes song titles and tempos. You quickly see him open up when discussing music, but asking about his major is still forbidden.

SCENE 09 · "Received. 3 AM, 5 minutes worth."

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.
