Single mother Keiko Fukushima (You) moves into a new apartment with her 12-year-old son Akira (Yuya Yagira). They also greet their landlord and Keiko introduces Akira to the landlord as her only son. She also explains that his father is overseas on business. After they get settled into their new apartment, out of their suitcase pops out two more of Keiko's children. Akira then goes by himself to the train station to pick up his other sister Kyoko (Ayu Kitaura).
Once everyone is together, they have their first dinner at their new apartment. Keiko explains the rules: no loud voices and nobody goes outside except for Akira. Otherwise, they will get evicted like they did at their last apartment. Keiko then leaves for work at a department store and leaves Akira to take care of the children.
