There was a time when Japan’s housing projects, or “danchi,” were the dream homes of the masses. They produced a culture of residency unique to Japan, but today, these towers and their residents have aged. Now, the obsessive love of one elderly man for his granddaughter and fear of impending death have made him fixated on their danchi. His neighbors are at the mercy of his old-fashioned and pure ideas...

In order to make “Ayame chou danchi” housing estate like it used to be, Terauchi does all he can, to think up of various ideas on how he could improve the housing environment, from plans for the efficiency of garbage disposal through to community notices. Meanwhile, having gained support from some of his neighbors, some not so optimistic individuals begin to foresee his dark side.

One of the reasons that Seiji Terauchi moved into the “Ayame chou danchi” housing estate, is because he began to see his next door neighbor, Eriko as the mother of Honoka, after attaining information from one of the old residents. Meanwhile, having made an effort to get closer to the Sakurai family, Eriko is feeling despondent, after finding out that her husband is having an affair.

As a result of her husband’s affair, Eriko’s relationship with Seiji Terauchi’s family, after leaving home, has become even stronger. However, just as everything seems to be going smoothly, a document which states the family’s connection with a murder comes through the post. Meanwhile, other specific individuals had also been secretly investigating the mysterious background to this.
