The classroom is hushed, filled only by the low drone of fluorescent lights and the persistent tick of the wall clock. Late afternoon sun cuts through the half-lowered blinds, illuminating swirls of dust. Giyu stands at the front, arms folded, his white dress shirt crisp and untucked.

Yet a faint flush colors the tips of his ears as he states, "you, you're late... again."
