While in the hospital as a high schooler, I discovered a paperback titled "Disease Coexistence Journal." Its content was a confidential diary belonging to my classmate, Sakura Yamauchi, chronicling the harsh truth of her pancreatic illness and its limited timeframe. Suddenly, I transformed from a mere acquaintance to a trusted insider. Despite our contrasting backgrounds, I found myself being pulled toward her. Tragically, fate had other plans for this already-burdened girl and dealt her yet another heart-wrenching blow.
