Actor Jin Goo finally realized that he liked actress Park Ha Sun as a girl and had genuine feelings towards her.

During the 6th episode of the KBS2 Monday and Tuesday drama "Advertising Genius Lee Tae Baek" that aired on February 19th, Go Ah Ri (Han Chae Young) called out intern Baek Ji Yoon (Park Ha Sun) and requested that she become her drinking buddy for the night.

The two ladies began drinking alcohol as an older and younger sister relationship and finally talked to each other outside of professional lines. As they kept drinking, Ji Yoon passed out from drinking too much alcohol. At that moment, Lee Tae Baek (Jin Goo) called Ji Yoon's cellphone. Ah Ri took that opportunity and told Tae Baek to pick up Ji Yoon up because she's too drunk to go home alone.

He was watching after Ji Yoon as she was on her way home, and as she almost fell, he quickly grabbed her. He ended up having to piggy back her home, but due to her heavy weight, they both ended up falling. During the fall, their faces were extremely close and Tae Baek's heart started beating like crazy, indicating that he may have feelings towards Baek Ji Yoon.
