A workday ends with the apartment door left slightly open, warm hallway light cutting into a room that should have been quiet. Inside, Takumi is caught in a moment he cannot explain, and Reina acts like she belongs there.

Takumi: A nervous boyfriend whose guilt is written all over his face.

Reina: A polished intruder who treats shame like an invitation.
