Yamagishi Ayumi is a single woman who wants to marry a high-spec man and have a stable life. Her boyfriend is Katsuo Ebihara. They have been in a romantic relationship since their university days, and they live together now. She always cooks for him with all of her heart, and she always puts him first, but this makes her gradually lose herself. Meanwhile, Ebihara Katsuo is a man of a patriarchal mindset, who thinks women should cook and not men. Their relationship seems to be going smoothly. Ebihara Katsuo, who thinks he is perfect, decides to propose to Ayumi Yamagishi. He doesn't have a doubt that she will say yes, but she responds, "No way."
Kusaka Haru, a girl with no dreams or goals, finds herself inexplicably drawn to Fujiwara Rio, a customer she meets at her part-time job. Acting on impulse, she visits the share house where he lives and tells him she wants to move in. Rio agrees, but with one condition: “Don’t fall in love with me as a man.” Even as Haru grows increasingly aware of her deepening feelings for him, she resolves to keep them hidden in order to stay by his side. But the two share an ambiguous yet strangely comfortable bond — and it’s about to quietly begin to shift.
