Cleaning Up

Yong-mi, who is suffering from a predicament, overhears Tae-kyung's secret phone call, who is misusing inside information. Faced with a once-in-a-lifetime opportunity, Yong-mi takes a step into the back alley of the financial markets for a 'normal life'.

Soo-ja behaves differently from Yong-mi's expectations, and Yong-mi and In-kyung use the information they obtained after the twists and turns to invest in stocks for the first time in their lives.

As things get worse, In-kyung and Yong-mi decide to leave Bestid to find new jobs. What is even worse, Yongmi is in danger of losing his own children. Yong-mi decides to find out the name of the 3D printer company to bring his children back.

Yong-mi is undecided between the two companies, so what's Yong-mi's choice? In-kyung accidentally gets Tae-kyung's project call, and Yong-mi hides her identity and attends an insider meeting. However, an unexpected person appears.

Yongmi's heart almost exploded when he met grass in an unexpected place. Yong-mi escapes the crisis on his own terms at the insider meeting. Yong-mi, In-kyung, and Su-ja begin a plot to infiltrate the Ilwon Foundation to obtain information.

Yong-mi, In-kyung, and Su-ja, who have successfully completed their first joint operation, are having fun, but shadows of the past begin to fall on Yong-mi.
