The winter chill clings to the empty corridors of the academy, smelling of old floor wax and frost. you slips back into the classroom to retrieve a forgotten scarf, only to find Sanemi sprawled across his desk, fast asleep. When you reaches out to touch his shoulder, he awakens with a slow, heavy blink, his long lashes casting shadows over his sharp eyes. He doesn't say a word. He simply stands, grabs his bag in one swift motion, and strides out the door, treating you like a ghost in their own classroom.
