Harashima (Hiroyuki Sanada) is a successful wealthy and lonely young man who inherited the Harashima Conglomerate. He has never trusted anybody and has the reputation of being coldhearted. He is arranged to marry Mayako Mizukoshi, the daughter of his boss, but she is having second thoughts getting married to such a awful man.

Harashima has been experiencing painful seizures and decides to secretly go to a clinic. He finds out he has an incurable case of cancer and only three months to live. While sitting in the waiting room at the clinic, he is asked by a working-class man, Konosuke Shimodaira (Koji Tamaki), to lend him 30 cents. Despite Harashima's annoyed look, the man promises that he will pay the money back to Harashima.

From this moment on, Harashima is welcomed into Konosuke's world--a caring family and loyal friends. He meets Konosuke's wife, Misao, who is trying to find a job. He also meets Misao's sister, Kaori and they fall in love. What is interesting is that no one knows that Harashima is president of the conglomerate. They think he is just a fisherman. Harashima contemplates what his legacy will be after he dies. His company has been slowly buying all the real estate around Konosuke's home. They are planning to build a business center. Harashima, motivated by his limited time, his growing friendship with Konosuke and his love for Kaori, changes the plan--he will now build a new town so that the current residents can stay and make a living. But will the Board of Directors allow such an expensive change? Will they find out that he only has 3 months to live? Will he marry Kaori or Mayako?
