On the 7th episode of SBS's Monday/Tuesday drama "The Mystery Housemaid" (Script Paek Yoon Chul, Director Kim Hyung Shik) broadcast on the night of October 14th, the kids asked about Park Bok Nyuh's family (played by Choi Ji Woo).
However, Park Bok Nyuh declined, "Sorry but I can't tell you any personal information." Afterwards, the kids went to Director Hong (played by Kim Hae Sook) and found out that Park Bok Nyuh had a husband and child.
Eun Doo Gyul (played by Chae Sang Woo) asked, "Ms. Bok Nyuh, do you have a husband and a child?" Eun Sae Gyul (played by Nam Da Reun) followed, "Did your family frequent the amusement park? Why did your family die?" Park Bok Nyuh replied, "I killed them" and the kids were shocked.
The kids returned to Director Hong (played by Kim Hae Sook) and asked her to answer yes or no. When asked, "Ms. Bok Nyuh's dead family members are her husband and son," Director Hong said yes.
At this time, Park Bok Nyuh came in. She caught on that the kids were hiding in the room and said, "Please don't say anything. You happen to be here so I'm telling you. I can't tell you anything from now on. So long." She then left.
