Takenouchi plays an aquarium employee named Kengo, who seems ordinary at first glance but actually possesses a secret that he would sacrifice everything in order to protect. Meanwhile, Ueto plays Risa, a young woman working in the sex trade in order to pay off her brother's debt, though her situation has led her to contemplate suicide. These two characters, both full of despair, meet each other and end up entering a contract marriage purely for its benefits. However, as they overcome various troubles, their relationship begins turning into true love.
