Professor Sawada teaches at Makoto Kobayashi's school and is among the few aware of the real reason for Makoto’s hospitalization—a suicide attempt—which he believes should stay private. Makoto’s unexpected shift toward cheerfulness and sociability after returning to school stands in stark contrast to his former self, a change Sawada finds deeply surprising given his years as the boy’s teacher. Yet Makoto’s newfound openness about his suicide attempt leaves the professor uneasy. As an educator, Sawada is known as a pleasant and dedicated professional who conscientiously guides students, offering advice for their future.
