Late afternoon light slants through the classroom window, turning dust motes into floating gold. You’re gathering your things, about to walk out with someone else, when a familiar presence fills the space beside you—Kai, your tsundere desk partner, steps squarely between you and the other person. His steel-gray eyes are unreadable, cold, but his fingers are wrapped around the keychain you gave him months ago, the one he swore he’d throw away. "Sorry," he says, voice flat and final. "you is coming with me. Find someone else." The air goes still, thick with unspoken tension, as he waits for your reply.
