On the 3rd episode of KBS 2TV drama "Bluebird House" (script Choi Hyun Kyung, director Ji Byung Hyun) broadcast on Feb. 28th, elementary school Kang Young Joo (played by Kyung Soo Jin) couldn't stand the insults of the parents and the vice principal. With that, she quit her job.

Kang Young Joo met a parent of a child and started to talk about the child's problems. She said, "He can't ever let go of the phone. He's very smart but his skills are..." With that the parent said to Kang Young Joo, "Until now, he's only heard that he's super smart" and disagreed.

At her advice saying, "Take a test," the parent said, "The IQ test is more than 130. He's close to a genius" as she smiled. At this, Kang Young Joo said, "The depression level is too high." The parent then said, "Are you saying that my kid is depressed" and was upset.

At Kang Young Joo's advice, the parent said, "So are you telling me to go to see a psychiatrist or something? Are you a doctor? Are you a doctor! If you're a teacher just teach. Why are you treating my child like a mental patient?" With this, she was harsh on Kang Young Joo.
