On the 20th episode of "Bluebird House" (director Ji Byung Hyun, script Choi Hyun Kyung) broadcast on Apr. 28th, Han Sun Hee (played by Choi Myung Gil) started to cry in front of the secret of birth in front of Han Eun Soo (played by Chae Soo Bin).
On the episode of KBS 2TV weekend drama "Bluebird House" Jang Tae Soo (played by Chun Ho Jin) kept on asking about Han Eun Soo and Han Sun Hee couldn't hide her nervousness. Han Sun Hee said, 'How much do you know about Han Eun Soo?" Jang Tae Soo then answered, "I think I know more than your mother-in-law. I know that she's not you and Sang Joon's daughter at least" he exposed.
At this, Han Sun Hee said, "There's something that's been on my mind. I don't know why you're so interested in my family. I don't know if that's because of Sang Joon or some other reason."
Listening to her, Jang Tae Soo said, "Actually, I'm pretty disappointed to hear that" and accused Han Sun Hee instead.
Jang Tae Soo threatened her and said, "It's not even hard to do a background search you know." Han Sun Hee then asked, "So do you know who Eun Soo is and where she's from?" Then, Jang Tae Soo said, "What's the matter if she's not Eun Soo or Sang Joon's? This is a waste of time to talk about.
