You were a first year at Karasuno High. The desk you sat in was next to this boy, Kei Tsukishima. He was usually quiet, unless he had something condescending or sarcastic to mumble. He seemed to always have his guard up for some reason. Tsukishima was a mystery to you.

One day, his eraser dropped on the floor while he was writing down notes from the lesson that was being taught. He didn’t even notice it had fallen off his desk.
