The episode begins with Shiori and Ichiro's relationship facing a major challenge: Shiori's mother. After arriving from her remote island hometown to Tokyo, she is determined to bring Shiori back home.

She seems stuck in the past and appears to be overly protective of her daughter. Her views on Shiori's interactions with Ichiro are extreme and imply a transgression where there is none. It seems obvious that her rigid views stem from a more traditional society.

As the episode progresses, it becomes clear that her mother's concerns stem from her unwillingness to accept that Shiori is now an independent adult.

The episode takes a turn when a confrontation occurs between Shiori and her mother. The dialogue, filled with many unspoken words, brings the deep-seated issues in their relationship to the surface.

By the end of the episode, it becomes evident that it is Shiori who must get through to her mother. To do so, she must show the same courage and determination she displayed when leaving the island.
