Satomi is 33 years old and a teacher of Japanese history at a prestigious private high school. By anyone’s standards, she has both talent and beauty but has been dubbed Ms. “Party of One” for wanting to do everything completely on her own. Work has been pretty hectic for her of late, and she has no time nor inclination for romance. But at a welcoming reception for a handsome new teacher 10 years her junior, Shinichi, she winds up releasing built-up tension in her life by getting very drunk. When she awakes the next morning, she is greeted by a terrible hangover and the sight of Shinichi, lying on the floor! (Source: TBS)
