On the MBC Wednesday/Thursday mini-series "Angry Mom" broadcast on Mar. 19, Jo Gang Ja (played by Kim Hee Sun) transformed into a high school student to protect her daughter Oh Ah Ran (played by Kim Yoo Jung)

On this day, Gang Ja was determined to help her daughter at school in the most direct way possible. Thus, she went to her high school friend Han Gong Joo (played by Go Soo Hee) for help as Gong Joo helped her create a new identity and look. Afterwards, Gang Ja successfully infiltrated into Myung Sung High School where Ah Ran was attending.

On this day, Gang Ja said to her fellow classmates, "My name is Jo Bang Wool" and sat in the seat where Ah Ran sat. Here, Gang Ja was shocked by the graffiti that was on the desk. It stated that she was a prostitute, a lesbian, and that she was like a rag.

After this, Gang Ja started to talk to Wang Jung Hee (played by Lizzy) who had been picking on her. She asked, "Did you do this?" and was angered. At this, Jung Hee said, "Some really idiot girl was sitting here and that's why I did this," as she mocked the situation.
