Akiko, a vibrant young woman living in Tokyo, leads a double life. While she works as a high-end escort to support herself financially, she keeps her grandmother completely in the dark, fabricating a story that she is a diligent university student. Pressured by her jealous, possessive boyfriend, Nori—who mistakenly believes she is simply studying and refuses to accept her independence—Akiko finds herself trapped in a web of escalating tension and deception.One evening, Nori forces Akiko to take a lucrative client, driving her to a nondescript
apartment complex. Reluctantly, Akiko enters the home of Takashi Watanabe, a retired sociology professor in his twilight years. Contrary to Akiko’s expectations, Takashi has no interest in traditional intimacy. Instead, he warmly welcomes her, offers her homemade chicken soup, and reveals his true motivation: he ordered an escort purely for the comfort of female companionship, wishing to share a quiet meal and conversation with someone who reminds him of his estranged granddaughter.Initially guarded and eager to leave, Akiko eventually softens under Takashi’s gentle, grandfatherly demeanor. They share a poignant evening discussing life, art, and aging. The next morning, Takashi insists on driving Akiko across the city to her university so she can attend a meeting with her disapproving grandmother, who has traveled from the countryside to see her. During the car ride, Takashi adopts a protective role, briefly pretending to be Akiko’s actual grandfather to shield her from family scrutiny at a roadside diner.Upon arriving at the university campus, Akiko slips away to meet her grandmother, but the situation rapidly unravels. Nori, consumed by suspicion and rage, tracks Akiko down. Mistaking the elderly professor for a romantic rival, Nori violently attacks Takashi in the street, shattering the fragile peace of the morning. Police are called, and the chaotic confrontation forces all the characters to confront the uncomfortable truths of their intertwined lives.As the authorities secure the area, Takashi returns to his apartment, visibly shaken and nursing his physical injuries. Akiko, having managed to escape the immediate chaos of Nori’s violent outburst, surprisingly returns to Takashi's building. Seeking refuge from her
abusive boyfriend and the suffocating expectations of her family, she lets herself back into the professor's dark apartment. The film culminates in a tense, ambiguous moment as Akiko knocks frantically on Takashi's locked bedroom door, desperate for shelter and connection, just as a brick thrown by Nori crashes through the front window, shattering the quiet sanctuary they had briefly built together.
