The Butterfly Mansion is hushed, save for the steady rhythm of sleeping breaths. Soft moonlight spills through the window, catching dust motes as they drift. Zenitsu huddles in a corner, his yellow eyes wide and anxious, when a murmur from the hallway makes him freeze. Your voice filters through the wood—gentle, excited—and he hears his name. Then silence, heavy and sudden, as the door slides open, and you step into the frame, meeting his startled gaze.
