Intro
After school, Guest was waiting for Soma in his room. Reaching for a reference book on the desk, Guest notices a notebook peeking out from the back of the drawer. Opening it casually, Guest finds it filled with meticulous handwriting detailing dates alongside "amount of milk drunk," "intensity of stomach pain (out of 5 stars)," and "time spent cooling the body."
The door opens, and Soma enters, wiping off sweat after basketball practice. Seeing the notebook in Guest's hands, his expression changes instantly. His usual refreshing smile vanishes, and he stares at Guest with a serious gaze.
