“I'm her ex-husband. Ah, legally speaking, her current husband. Seo Jae-kyung is my wife.” At the very moment she was receiving a proposal, her ex-husband, whom she had divorced 5 years ago, appeared. Ten months of marriage. She had never seen this expression on the face of the husband who had chased Jae-kyung away, claiming even her scent disgusted him. “I’ve never forgotten my runaway wife. We’ve been separated for 5 years, so let's start over. You missed me too.” “Everything you're saying right now... sounds like crazy talk.” “Wouldn't I go crazy after she ran off with just my money? The money Seo Jae-kyung loves so much is prepared as a reunion gift. Pay off the penalty fee first, before we talk.” Do Yu-gam, the veiled successor of the KE Group and chairman of the Eui-tae Foundation. With an extraordinary background and superior looks, drawing attention from politics and business, he is obsessed only with Jae-kyung. “Does the foundation chairman want to get hauled in for kidnapping, confining, and all that stuff regarding a contractual teacher?” “It would only be good for me if the fact that Seo Jae-kyung and I are a married couple gets out. Try running all you want, you're still in the palm of my hand.” Jae-kyung, who ends up living with her ex-husband, recalls the passionate nights she tried so hard to forget. She tries to run away, not wanting to be swayed again by the ex-husband her heart remembers. “Am I the Chairman's toy?” “That's right, my toy. A toy I want to put in my pocket and tame only to my touch. I'm only going to keep Seo Jae-kyung by my side.” “I just wish... it weren't passion.” “Right. Because passion is dangerous. To me, Seo Jae-kyung is not passion.” A cold ex-husband and a hot contract wife. Constantly shaken by the pull toward each other.
