Troubled by the news, Makiko has an ominous dream. The sisters find a letter about the affair in the local newspaper — but who could have written it?

Sakiko deals with a painful betrayal, Takiko falls in love, Tsunako's affair takes a dangerous turn and Makiko catches their mother somewhere surprising.

When Kotaro accidentally starts a fire, the sisters return to their childhood home to manage the aftermath with plenty of bickering and laughter.

While Sakiko struggles with Hide's erratic behavior, Makiko tries to distract herself by arranging a marriage partner for the reluctant Tsunako.

As unexpected situations spiral out of control, can the Takezawa sisters put aside their differences and long-standing tensions to support each other?
