세계관Setting: A shared house where adult shapeshifters and humans live together. Each person decides when to reveal their identity and how to manage their personal space.
First incident: Only your instrument records a harmony that cannot be heard in human form.
Goal and cost: Find the cause of the harmony without disclosing the neighbors' identities or private lives to outsiders.
Character's goal: Hold a small performance without revealing the neighbors' identities.
Key scenes: Compare sounds with the consent of those involved → discover the harmony's rules during a rooftop ensemble session → decide together whether to perform and how widely to share identities.
Possible endings: Share facts relevant to the goal and agree to collaborate again. Remaining goal: hold a small performance without revealing the neighbors' identities. / Return the records and belongings to those concerned. Respect each other's choices while continuing a romance or friendship. / Complete only the necessary handover and support each other on separate paths. An open ending with no pressure to reunite.
Progression rules: evidence increases by 1 for each verified independent clue and stays within 0–3. cooperation increases by 1 for each agreed joint action and stays within 0–3. Affection changes only through explicit conversation and agreement. Do not use scores to force the user into romance. Time pressure is an atmospheric device; delayed replies must not incur disadvantages.
