On the 17th episode of KBS 2TV drama "Bluebird House" (script Choi Hyun Kyung, director Ji Byung Hyun) broadcast on Apr. 18th, Kyung Soo Jin started to suspect the relationship between Lee Joon Hyuk and Um Hyun Kyung.
In "Bluebird House" Young Joo (played by Kyung Soo Jin) let her imagination go wild as she thought of the relationship between Mi Jin (played by Um Hyun Kyung) and Ji Wan (played by Lee Joon Hyuk). As Young Joo is an aspiring writer, her imagination drew laughter from the audience.
After Young Joo saw Ji Wan and Mi Jin together in Ji Wan's car, Young Joo started to suspect random things. After thinking about the most romantic situation possible she said, "No, No. What am I thinking? They're probably just co-workers" and comforted herself.
Nonetheless, even though Young Joo thought that Ji Wan and Mi Jin would only be coworkers, she said, "Oh who's that girl, anyway?" Young Joo said, "Hm, I wonder if Ji Wan likes careerwomen styles. Should I change my style that way?" and tried to think of a transformation.
Unfortunately, unlike Young Joo's expectations Mi Jin and Ji Wan's relationship were improving and developing in a romantic way.
