Zhen Ping (played by Tamura Masakazu) is a university professor engaged in marine biology research. He lives alone with his daughter Mi Jiu (played by Matsu Takako). To celebrate Mijiu's 20th birthday, they met for dinner, and Mijiu went to the appointment in her mother's dress.

Before dinner, Zhenping told Mijiu the secret he had hidden for many years: Mijiu was originally the child of his wife Ricardo and her ex-husband, and they were not related by blood. Ji Ping promised Ricardo to tell Mi Jiu the truth when he turned 20. Mijiu was shocked by the news.
