Tsuma wa kokuhaku suru (1961)

Caizi, a poor female student, is forced to marry Liangji Takagawa (Rongtaro Ozawa), an associate professor of medicine who works in a university, but there is a big gap in their character and age, and their married life is not harmonious. Kaichuan student Yukoda (Hiroshi Kawaguchi) walks into their lives at the right time, which makes Caizi feel relieved and endure more pain. One day in summer, Takagawa went to Beisui Takashi Valley for rock climbing with his wife and Yoshida. Takagawa slipped and fell, and the lives of the three people were in danger. Caizi finally cut the rope, causing him to fall off a cliff and die. After the arrest of Caizi, there was a heated debate between the two sides in court over whether Caiko was deliberately murdered. As the parties, Katsuko and Yukoda also had to face their true feelings. ©Douban
