Yuta, a man running a small company, falls deeply in love at first sight with Kana, whom he meets through a slave auction, and takes her as his wife. Though he loves her profoundly, years of servitude have left her emotionally distant, with little expression or response. As their love grows increasingly unbalanced, Yuta suffers a devastating financial loss and goes bankrupt. Desperate to bring in even a little income, Kana resolves to sacrifice herself. Yuta struggles desperately to save his wife, but Kana harbors a secret she must keep hidden from him.
