One the Woman

Yeon Ju is an elite prosecutor, and her goal is to become a chief prosecutor. Therefore, she wants to investigate and catch the fraud that the deputy chief of her division failed to. Meanwhile, Mi Na is left out of her family and in-laws just like any other day and attends an art auction alone. As they are fated to, Yeon Ju sees Mi Na and gets shocked as she looks exactly like her.

When Yeon Ju wakes up at the hospital, the doctor tells her that she has retrograde amnesia due to a car accident. Yeon Ju is thrilled to find out that she is part of a wealthy family, but at the same time, she feels suffocated when she is around her in-laws. While she's feeling gloomy that no one in her family actually cares about her, she meets Seung Wook.

After Yeon Ju threw a fist towards her in-laws at the remembrance service, a rumor spreads about Yumin Group’s heiress having a psychological problem. Sung Hye takes this as an opportunity, and she holds an emergency shareholders’ meeting to impede her from getting an inheritance. Meanwhile, Hanju family gets shocked to find out the major shareholder of the Yumin group.
