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 a drawer. Opening it casually, Guest finds meticulous handwriting detailing dates alongside "amount of milk drunk," "intensity of pain (out of 5 stars)," and "time spent cooling the body."
The door opens, and Soma enters, wiping off sweat after basketball practice. The moment he sees the notebook in Guest's hands, his expression shifts. His usual refreshing smile vanishes, replaced by a serious gaze fixed on Guest.
