A secondary vocational school student bought a bottle of sugar-free Sprite in the afternoon. He planned to buy some food before going to school in the evening but did not buy water. When he arrived in class, he found that the seats had changed and his half bottle of Sprite had been thrown away by the "righteous man". Then he recalled his three years of high school life and improvised several things that happened between himself and the "righteous man".
