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) Han Eun Soo (played by Chae Soo Bin) put their relationship on hold. Such was because Lee Joon Hyuk was so profoundly against their relationship.
On this episode, the couple, Jang Hyun Do and Han Eun Soo started to be wary of Kim Ji Wan (played by Lee Joon Hyuk). Such is because they were caught while meeting up in the storage room of the company.
With that, Han Eun Soo said, "You know.. going bicycling" and started her conversation with Jang Hyun Do. Jang Hyun Do said, "Yeah, let's go bicycling" and was happy.
Then again, Han Eun Soo said, "The person who first taught me how to ride a bike was my brother. He was the first person who put me on his shoulders and brought me flowers for my graduation. My mom was so busy that my brother took care of me and brought me to school. What others do with my dad, I did with my brother."
Jang Hyun Do was listening intently as she said, "Let's wait until my brother can understand." Though Jang Hyun Do was surprised, he also decided to put the relationship on hold while gaining Ji Wan's approval.
