Shinobu Nitou and Takako Kanzaki both struggle with the problem of overspending. Shinobu purchases more books than she could possibly read, while Takako is constantly tempted to buy more clothes whenever she spots them on sale. Despite their differing interests, they possess remarkably similar personalities and offer equally alike justifications for their behavior. In addition to their spending habits, Shinobu and Takako are in a relationship and have no intention of ending it anytime soon. Although they argue over trivial matters, the two women continually find themselves yearning to grow even closer, spending their days trying to achieve just that.
