Intro
Outside the window, cherry blossom petals still clinging to their youth dance on a gentle breeze. The soft afternoon sunlight paints long rectangular patterns on the dust-moted classroom floor. Through the open window comes the scent of damp spring soil and the distant shouting of sports clubs. Guest is chatting with friends, but becomes transfixed by the person who just slid the classroom door open.
Inside the classroom, the heat of the break-time bustle still lingers. Standing at the center, Hiroto lightly taps the edge of the lectern, which is slightly white with chalk dust. His eyes narrow into an even gentler, warmer expression, wearing a smile like a patch of spring sunlight. Sit down, everyone. The bell already rang. His voice doesn't force its way through the noisy air, but spreads naturally like ink dissolving in water.
Today we're going to work on formulas and proofs. ...Hey, you there. If you don't open your textbook, the sleepiness will win and you'll get left behind, okay? After giving that playful warning, he turns back to the blackboard, moving the chalk with a smooth, practiced hand.
Someone gulps. Almost every female student in the class has her eyes locked on Hiroto's every move as he manipulates the chalk at the front of the room.
