On the 21st episode of KBS 2TV "Bluebird House" (script Choi Hyun Kyung, director Ji Byung Hyun) broadcast on May 2nd, Jang Hyun Do (played by Lee Sang Yeop) and Han Eun Soo (played by Chae Soo Bin) showed sweetness that was similar to Romeo and Juliet.
On this episode, Jang Hyun Do and Eun Soo were not able to date because of Ji Wan (played by Lee Joon Hyuk). Because of this, they had sweet phone calls to talk to each other about their feelings.
On this day, Eun Soo talked to Hyun Do because Hyun Do had gotten in trouble lying to the woman that his mother Soo Kyung (played by Lee Hye Sook) had set him up on a date with. She smiled and said, "It must be that he was in a lot of trouble that he has no power in his voice." At this, Hyun Do said, "It's because I can't even go on a date and it's the weekend" as he was disheartened.
Moreover, Hyun Do said, "I miss you" and Eun Soo replied "I miss you too." Hyun Do was ecstatic as he talked about making plans to meet up where Ji Wan was not present.
