The day Aiko and Reina move into their own home together is supposed to be a joyous occasion. However, with Reina working five to six days a week, Aiko the budding housewife finds solitude tough to handle. She jumps headlong into making friends at the nearest lesbian get-together but meets one person not interested: Reina's bitter ex-girlfriend, who fills her emotional void with activism and her love for all-female musicals. While Aiko establishes herself as the queen of domesticity, Reina is nominated for a promotion at work. She soon discovers that being a woman in the professional world is rife with injustice, and begins to resent her gender and the way society treats it. With her ex-girlfriend now hanging around, it is a cold reminder as to what happens when Reina becomes a thorn in other women's families. Living together will give Aiko and Reina challenges never dreamed of before, yet it gives them the chance to build a life together, other women notwithstanding. Their first trial is to navigate the first few months of coming out, disappointment, glamorous show tunes, and a dark cloud of kataomoi, or "unrequited love," hanging over the city.
