Since his wife died, Masahiko has raised his daughter Hitomi by himself. Hitomi is now all grown up and an adult, but they still live together and rely on each other. On New Year’s Day, they talk with each other like they usually do, but they both reveal bombshell news. Hitomi tells Masahiko that she is going to get married in 3 months. Masahiko tells Hitomi that he was informed that he has only 3 months left to live. They are both shocked by each other’s news.Masahiko is strongly opposed to his daughter’s marriage because her future husband is an unpopular comedian and is 10 years older than her. Meanwhile, Hitomi tries to persuade her father to get medical treatment. Because they want each other to be happy, they can’t give up their position and try to persuade the other person. In the end, they decide they don’t want to waste the next 3 months and write down things they want to do. Hitomi writes down things she wants to do before she gets married, and Masahiko writes down things he wants to do before his death.(Source: AsianWiki)
