On the 11th episode of KBS 2TV weekend drama "Bluebird House" (script Choi Hyun Kyung, director Ji Byung Hyun) broadcast on Mar. 28th, the possibility was raised that Han Eun Soo (played by Chae Soo Bin) was the daughter of Jang Tae Soo (played by Chun Ho Jin), which raised the tension of the drama.
On this episode of "Bluebird House" Jang Tae Soo (played by Chun Ho Jin) started to have suspicions that Han Eun Soo didn't follow her father's last name but her mother's last name. At this, Lee Jin Yi (played by Jung Jae Soon) said, "I don't know why they don't have any thoughts like that. They're only smart on the outside." With that, she even told them what Han Eun Soo's age was. Thinking about Han Eun Soo's age, Jang Tae Soo started to think about something in depth.
In addition, Shin Young Hwan (played by Nam Kyung Eup) was asked for advice by Han Sun Hee (played by Choi Myung Gil). He said, "There's only one solution. Just tell Eun Soo the truth." Hearing these words, Han Sun Hee didn't know what to do in front of Han Eun Soo. In the end, Han Sun Hee was not able to do or say anything to Han Eun Soo.
