Sayo is a faithful wife who supports and devotes herself entirely to her husband. In contrast, her best friend Emi has a free-spirited personality, completely opposite to Sayo's. Despite being married, Emi harbors intense romantic feelings for Fujiwara, a man from her volunteer group, and frequently forces Sayo into listening to her love troubles. However, Fujiwara's true feelings are directed toward Sayo—he secretly cherishes hidden romantic desires for the gentle and modest woman.
