Actress Han Chae Young doesn't know the true identity of who Park Ha Sun is, and she asked her to take care of Jin Goo.

During the 6th episode of the KBS2 Monday and Tuesday drama "Advertising Genius Lee Tae Baek" that was broadcasted on February 19th, Go Ah Ri (Han Chae Young) had several drinks with the new intern Baek Ji Yoon (Park Ha Sun).

Go Ah Ri proceeded to ask Baek Ji Yoon a favor and asked, "are you close with Lee Tae Baek (Jin Goo)?" He's really such a good person. Do you think that you could support him and be by his side?" She wanted Ji Yoon to support and take care of him. Ji Yoon was taken by surprised and said, "we're just simply friends, nothing more than that."

Ah Ri replied to Ji Yoon, "I didn't ask you to meet with me to just ask you of this favor. Will you become my drinking friend from now on?" After they discussed that, they began talking like good friends and stepped out of their professional limitations. It seems as though they are now able to somewhat support each other and have friendly conversations outside of their working zone.
