At a factory workplace, a kind and gentle man discovers a mannequin destined for disposal. Captivated by its pure, innocent appearance, he takes it home and names it "Kana." When he talks to it, he begins to feel warmth and affection as if he were with a real lover, gradually developing deep emotional attachment. He brings Kana along on drives, even to weekend work, and spends every night together with her. Their bond grows stronger each day, just like a real couple in love.
