On the episode of KBS 2TV weekend drama "Bluebird House" (script Choi Hyun Kyung, director Ji Byung Hyun, Hidden Picture Productions) broadcast on May 10th, Kang Young Joo (played by Kyung Soo Jin) and Kim Ji Wan (played by Lee Joon Hyuk) started to follow Suh Mi Jin (played by Um Hyun Kyung).
On this episode of "Bluebird House", Kang Young Joo and Han Eun Soo (played by Chae Soo Bin) and Jang Hyun Do (played by Lee Sang Yeop) each had their own reasons for following Kim Ji Wan. With these reasons, they started to follow Kim Ji Wan and Suh Mi Jin.
Kang Young Joo had a crush on Kim Ji Wan. As Kim Ji Wan seemed close to Suh Mi Jin, she said, "How are the coworkers so close?" With that, she looked slightly upset. In addition, as Kim Ji Wan took a flower off of Suh Mi Jin's head, Young Joo said, "Well I guess you can do that for workers" and tried to rationalize such behavior.
Then again, as Kang Young Joo saw Kim Ji Wan and Suh Mi Jin at a hotel, Kang Young Joo was startled. She started to cry saying, "How the heck can coworkers go to a hotel? In the middle of a day?"
