In "Angry Mom," the truth was revealed that the person who was behind the school violence of Yoon Yae Joo and Kim Yoo Jung was none other than Kim Tae Hoon.
On the 4th episode of MBC Wednesday/Thursday miniseries "Angry Mom" (script Kim Ban Di, director Choi Byung Gil) broadcast on Mar. 26th, Jin Yi Kyung (played by Yoon Yae Joo) reflected on the past with Do Jung Woo (played by Kim Tae Hoon).
On this day, Jin Yi Kyung went to Oh Ah Ran (played by Kim Yoo Jung) who was admitted to the hospital. Jin Yi Kyung reminisced about the happy times that she had with Do Jung Woo. She said, "I thought that if I obeyed his words, he would like me forever. I thought he would protect me forever" and started to cry.
Oh Ah Ran said, "Now you know that's not true" as he said harsh words. Jin Yi Kyung said, "Regardless of how obedient others are, no one will protect you forever. Other than myself. Well then again there's another person. Regardless of how much you don't listen to me, you're always on my side." With that, she showed how appreciative she was of the support.
