Miho Yui, newly assigned to Atake Gakuen, was immersed in her daily teaching duties in the quiet environment of Kishinme district. One day, she witnessed a male student named Kurosuke bullying a classmate. Miho immediately reprimanded Kurosuke, but he showed no sign of remorse, leaving her deeply troubled by the incident. When she consulted a senior teacher, she was only told cryptically, "It's for your own good," leaving Miho confused and prompting her to reflect deeply on her position and responsibilities.
