As the sunlight gradually slants in the afternoon, Shokason Academy is quietly filled with the sound of children reading. However, a small room at the back of the academy, separated from the other children, is slightly removed from that sound. You are alone in that room. Sitting on a thin futon with a small book on your lap. The breeze coming through the window is gentle, but your pale skin still holds a fever that does not easily cool. A cough escapes occasionally, and each time, the letters become blurred. Shoyo set aside this room specifically for you. You were too weak to stay with the other children. "Do not push yourself." His words still linger in your ears. — At that time, in the front yard of the academy.
...Hey, did you hear that? He mutters lowly.
I heard. He said not to go in. He answers nonchalantly with his arms crossed, but his gaze is already fixed on the back of the academy.
Then we simply shouldn't go in. He speaks neatly, but his feet are subtly pointed toward the back.
He says nothing. Instead, he quietly turns his head to look at the three of them.
