Choi Ji Woo felt instinctively that Wang Ji Hae was behind the reason for Kim Hee Jung's death and started going left and right.
On the 13th episode of SBS Monday/Tuesday drama "The Mystery Housemaid" (Script Baek Woon Chul, Director Kim Hyung Shik, Nam Gun) broadcast on November 4th, Yoon Song Wha (played by Wang Ji Hae) hears that Eun Sang Chul (playe dby Lee Sung Jae) and Park Bok Nyuh (played by Choi Ji Woo) married and called out Park Bok Nyuh.
She said to Park Bok Nyuh, "Is it all if you use poor kids who are longing for a mother's touch. This is all an obstacle for kids too." She said these harsh words and Eun Han Gyul (played by Kim So Hyun) who came home asked her what had happened.
Park Bok Nyuh confessed, "I met Yoon Song Wha and that I'm an obstacle." Eun Han Gyul said, "Bok Nyuh, you said that you can be our mother so did you start talking about mother's will? Bok Nyuh, I have a favor. Please reveal that this woman can't be our mother," and asked for a favor.
Park Bok Nyuh acted like she suddenly thought of something and went to the café where she met Yoon Song Hwa and asked to verify the CCTV. She got the video of the day when Woo Sun Young (played by Kim Hee Jung) met Yoon Song Hwa.
Park Bok Nyuh saw this and called Yoon Song Wha saying, "Let's meet. I have evidence that the last person that Woo Sun Young met is Yoon Song Wha," and made Yoon Song Wha nervous.
