Forbidden Room Training 4 Secret Basement

In a park on a rainy day, high school girl Riri Takayama (played by Yoshitsune) was ruthlessly abandoned by her greedy boyfriend. Yoshihiko (played by Taro Yamamoto), a man lurking in the dark, took the unconscious Riri home. Yoshihiko, who was once a homeless man, has lost his memory and voice. He can only communicate with others using pen and paper. Later, he was adopted by the wealthy woman Misugi Takako (played by Hariko Kato) and lived in a luxurious Western-style villa. Takako fell ill and was hospitalized. The lonely Yoshihiko took Lili back and imprisoned him. No matter how scared and angry Riri was, he always showed gentleness and consideration. The two gradually get closer, and Riri also begins to understand Yoshihiko's lost memory... Based on the documentary "The Abduction and Breeding Incident of a High School Girl" by Matsuda Yusaku's widow, Matsuda Michiko.
