From delicious.com: "Unexpectedly complex story of a teacher being bullied by a student. Bizarrely endearing"
"What are you doing?" Keitaro was already calling, as he broke into a jog across the parking lot, his furrowed brow sharpening into a full-fledged scowl. "Stop that! Let him go!"
At the sound of an adult's voice the boys broke apart, milling away from the one at the center of the cluster in an effort to look casual. It was Nakamura, he saw, and supposed he should have known; the small boy had a purpled black eye, a trickle of blood running from his lip, and a dazed expression, and was groping vaguely for the pair of glasses lying on the asphalt not far from his hand. Keitaro strode into the semi-circle of teenagers and scooped them up, handing them to Nakamura and helping him to his feet.
