In "Bluebird House" Chae Soo Bin talked about the relationship between Lee Joon Hyuk and Um Hyun Kyung.
On the 20th episode of KBS 2TV weekend drama "Bluebird House" (script Park Pil Joo, director Ji Byung Hyun) broadcast on Apr. 26th, Kang Young Joo (played by Kyung Soo Jin) was shocked to hear from Han Eun Soo (played by Chae Soo Bin) that Kim Ji Wan (played by Lee Joon Hyuk) was dating someone.
On this day, Han Eun Soo was having a phone conversation with Kang Young Joo. She said, "You said last time you thought that my older brother was dating something someone. I think I know who that is" and talked about Kim Ji Wan's private life.
Han Eun Soo said, "That person would probably be Ms. Suh. I feel like she's close to my brother but in some ways she's really not." With that, she talked about Suh Mi Jin (played by Um Hyun Kyung). Kang Young Joo was confused because she wasn't sure what this had meant at all. Meanwhile, she showed that she wasn't crazy about this idea but she had a crush on Ji Wan. In addition, Han Eun Soo said, "At least I think she is interested in my brother" as she didn't read Young Joo's feelings.
