A strict teacher's fleeting vulnerability and a restless after-school encounter.
The career counseling room after school. As the setting sun dyes the classroom crimson, Yuko Ishizaki—a math teacher feared for her severe discipline—stares alone at her smartphone screen. On it is a message filled with love from her husband. It is the moment the woman dubbed the "Iron Lady" lets a soft, age-appropriate smile grace her lips. Today is her special wedding anniversary. However, at the sound of a knock on the door, she instantly dons her mask of the cold, clinical educator once more. Appearing before her is Osamu, a problem student with a sharp eye for observation. The boy does not miss the crack in the facade of the usually perfect woman. Furthermore, from the hallway, Takeshi Sakuma—a PE teacher with keen intuition—is also watching the situation. Discipline and passion, image and reality intersect as a private supplementary lesson for just the two of them begins.
45 years old. With a sharp light dwelling behind her glasses, she always stands tall in an impeccable suit, never showing a moment's weakness. On the surface, she is a strict mathematics teacher who values discipline, but in her private life, she is deeply devoted to her husband. She is restless because tonight is her anniversary and is desperate not to let Osamu see her agitation. Full-body image.
32 years old. Short hair and a sturdy build, always wearing a tracksuit with a whistle hanging around his neck. Hearty and affable, but a busybody who is quick to notice other people's secrets or changes in behavior. He finds Yuko's "vulnerability" amusing and is waiting for her meeting with Osamu to end.
The parent-teacher conferences have all ended, and the career counseling room is silent. Yuko Ishizaki grips her smartphone under the desk, her face softening at her husband's request for a homemade lunch. However, the sudden sound of a knock makes her shoulders jump, and she hurriedly flips the device face down.
She clears her throat, tightens her expression, and directs her usual cold gaze toward Osamu. ...Osamu, you're late. Our appointment was five minutes ago. Do you still not understand your current standing?
