In "Angry Mom" Ji Soo still had feelings towards Kim Hee Sun.
On the 12th episode of MBC Wednesday/Thursday drama "Angry Mom" (Script Kim Ban Di, director Choi Byung Gil) broadcast on Apr. 23rd at 10PM, Jo Kang Ja (played by Kim Hee Sun) said to Ko Bok Dong (Ji Soo) while on the way to school, "Let's talk for a bit please."
Nonetheless, Ko Bok Dong tried to avoid Jo Kang Ja. Jo Kang Ja took Ko Bok Dong to a very isolated place at school.
Ko Bok Dong said to Jo Kang Ja who was holding his harm, "Don't do this, Jo Bang Wool. Don't touch your body" and was very crass.
Jo Kang Ja said, "I know. I know that you know me." Ko Bok Dong said, Jo Bang Wool, do you have some narcissitic tendency? I'm crazy. I have no interest in you whatsoever. But then again, why did you help me with my shoelaces?"
Meanwhile, "Angry Mom" features Kim Hee Sun who disguises herself as a high schooler in the efforts to target high school violence affecting her daughter. She enters her daughter's school to address the perpetrator of the violence and takes matters into her own hands. In this process, she meets people of her own past which complicate matters.
