"Oi, Konekomaru—stop Shima for me!" Unhurried footsteps shuffled out the classroom, followed by a rush of multicolored streaks flashing out the door after pink hair. A milk carton stood at the teacher's podium and feet paused near it as bright blue eyes were caught by its unaccompanied state.
"Yukio?" the blue eyes shifted about, searching for three moles and rectangular glasses. The milk was unattended and Rin contemplated the danger, shrugged, then drank down roughly half of its contents. It went down cool and smooth and he placed it back on the podium without guilt, figuring he would need the jolt in height more than his younger brother. As soon as a soft voice called for his presence, blue spikes bobbed out the room, fingers locked behind his head. "Coming."
Suguro returned to the empty classroom with a frown twisting his mouth. "Damn Shima," scowling lips parted in a grumble, thoughtless fingers snatching at the seemingly abandoned carton of milk on the podium. It felt lighter than earlier yet his lips pressed against the strangely warm curve of the opening and he tilted the rest of it into his mouth.
