In "Bluebird House" Lee Sang Yeop and Chae Soo Bin showed a different type of date on the way home from work.

On the 9th episode of KBS 2TV "Bluebird House" (script Choi Hyun Kyung, director Ji Byung Hyun), Hyun Do (played by Lee Sang Yeop) and Eun Soo (played by Chae Soo Bin) showed that they might have feelings for each other.

On this day, one of the members of Hyun Do's band was insulting him. Eun Soo took Hyun Do's side. Hyun Do saw Eun Soo acting like this and was moved.

At this, Hyun Do waited until Eun Soo would finish up with work and it seemed like they would go home from work together. Nonetheless, he did not say that he would take her home in his car, which startled Eun Soo a lot.

Hyun Do started to follow the bus that Eun Soo was on and then would follow her down an alleyway as he made Eun Soo laugh.

Meanwhile, "Bluebird House" is about a younger generation who is going through troubles of unemployment and dealing with the stresses of reality. It also features the struggles of them and their parents in this societal commentary.
