Rien Tachibana is a full-time housewife supporting her husband who runs a restaurant. His work keeps him extremely busy, and they rarely get to eat together—only a few times a year at most. Over time, their marital relationship begins to grow cold. Feeling lonely, she starts going out frequently with friends for shopping and meals. Eventually, her friends organize a mixer, and she decides to attend. There, she meets a man whose warmth gradually stirs her emotions. As he fills the emptiness in her heart, she finds herself drawn to him, surrendering her feelings.
