High School Teacher

Due to family misfortune, female high school student Mayon Ninomiya (played by Sachiko Sakurai) has been living a life full of pain and depression. What has always supported Mayon to continue living is her strength and optimism. There is a new biology teacher in the school, a 32-year-old named Hamura Takao (played by Hiroyuki Sanada). One is a middle-aged man who is a role model for others, and the other is a pure girl who has just begun to fall in love. These two people fall in love. Finally, Cocoon's father learned of the illicit love affair between his daughter and the teacher, and he unscrupulously began to find ways to separate the two. How far can a relationship that violates ethics go? Cocoon and Takao are two kind-hearted people who never want to hurt others, but pain and sorrow have not left them away. Amidst tears and smiles, between love and hate, what will be the outcome of the struggling man and woman?
