"The Way of the Couple 2" features the same main cast from the previous season, with Takeda Tetsuya and Takahata Junko reprising their roles. The drama centers on the couple who run a tea plantation business, weaving a small-world stage that portrays the relationships between couples, parents and children, siblings, and neighbors—depicting the "trivialities of daily life = household affairs." Leading the cast are Takeda and Takahata as the couple, Takuno Kozo and Satoko. Other characters return from the previous season, including the children's roles played by: Shizuyo Deguchi of南海CANDIES (as the eldest daughter Natsumi), Masako Tadokoro (as the second daughter Yayoiko), Yuka Homma (as the third daughter Wakaba), and Yuto Suzuki (as the youngest son, Atsushi).
