Children Are Not Blessed From Anywhere

Haruko, the eldest daughter, is not good with meat and socializing. The second daughter, Natsuko, is a meek manicurist. The eldest son, Akito, is worried about his age in terms of entrance exams and girlfriends. They live apart from their parents in an apartment in a quiet residential area. One night, Haruko sees a ring on Natsuko's left ring finger and becomes furious. The reason why the eldest sister is against the engagement is related to the "past" of the siblings.
This is a new story of a family in search of their own peace.
