Ji-hye and Soo-kyeong are two women who are actively trading secondhand goods. Soo-kyeong’s trade errand sends her husband, Yoon-je, to make a secondhand deal with Ji-hye, who is also a sex coordinator. However, Ji-hye proposes a different deal to Yoon-je when she meets him. On the other hand, Su-kyeong gets a scent from Yeon-woo, whom she meets through her trading business, and they begin a different relationship. Yoon-je’s relationship with Ji-hye continues through secondhand trading, while Yeon-woo finds another fun in it with Soo-kyeong.
