Adapted from the novel of the same name, "The Farewell of 100 Million Yen" is a Japanese drama launched by NHK, starring Takaya Kamikawa and co-starring Hokuto Matsumura, Morita Motochi, and Seimi Yasuda.

Tetsuhei Kano (Takaya Kamikawa) is an office worker who works at a medical-related company, and his wife, Natsuyo (Seimi Yasuda), loves to buy all kinds of affordable things, and the two of them live an ordinary but happy family life.
One day, Xia Dai's relatives came to Tie Ping to borrow money, and Tie Ping learned the secret of Xia Dai's surprise.
30 years ago, Natsuyo inherited a huge inheritance from his aunt, and together with the profits from the stock, a total of 4.8 billion yen was deposited in a bank account, which was run by the lawyer Hosei Hosato (Masato Wada).
Xia Dai told Tie Ping that she never thought the money was her own, and she was afraid that the money would destroy her existing life.
Even though Tieping's mother died without money for medical treatment, she did not take out the money.
The pain caused by the poor life in the past made Tie Ping unable to understand what Xia Dai had done. The lawyer also found Tie Ping.
Tie Ping recalled when they first met each other twenty years ago.
Tie Ping fell in love with the gentle and smiling Xia Dai, but at that time Xia Dai cheated on a married doctor. Tie Ping thought about it for a long time and decided to show his heart that the two were together.
Tie Ping began to look back on the past and think about how to start a new life.
