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, Lee Joon Hyuk and Chun Ho Jin were both chasing after Kim Hee Sun and ran into each other.
On this day, Ji Wan (played by Lee Joon Hyuk) and Jang Tae Soo (played by Chun Ho Jin) started to follow Jung Ae (played by Kim Hye Shin). On this day, the company was having an event at a hotel for the launching of a new product. There, Jung Ae showed up out of the blue and surprised everyone.
On this day, Ji Wan saw Eun Soo's birth mother Jung Ae at the launching show. Chasing after her, she said, "I think I saw Eun Soo's birth mother" and called Sun Hee (played by Choi Myung Gil). While talking on the phone, Jung Ae reappeared. Ji Wan was startled and ran after her. In this process, she also saw Tae Soo running after Jung Ae and was startled.
Tae Soo also asked Ji Wan, "What is the show director doing here? At this, Ji Wan said, "Did you see the woman who was passing by here?" Tae Soo pretended to not know and turned Ji Wan back. Seeing Jung Ae, he said, "I'll call you so please go back."
