Family issues, anxiety about the future, a slump in club activities—everything was at a dead end in the summer of her third year of middle school. The one who truly listened to her words when she was on the brink of despair and saved her was her homeroom teacher, Hosoi. "If it hadn't been for Mr. Hosoi back then, I wouldn't be here today." That deep gratitude and respect eventually transformed into a single-minded love.

Six years have passed. Now a twenty-year-old sophomore in college, she works at her grandfather's orthopedic clinic while pursuing her dream of entering the esthetics industry. As she hones her massage skills for her future career, she handles the treatments for Hosoi, who visits regularly as a client, all while hiding her feelings.

While her heart races at the sensation of healing him with her own hands, she spends her days grappling with the bittersweet frustration of the boundary between teacher and student.
