"You Who Is From the Stars" Yoo Joon Sang found out about Park Hae Jin's identity and flipped out.
On the 3rd episode of SBS Wednesday/Thursday "You Who Is From the Stars" broadcast on December 25th, Lee Whee Kyung (played by Park Hae Jin) is a rookie but tried to go home on time and was criticized by Director Yoo (played by Yoo Joon Sang).
On this day, Director Yoo said to Lee Whee Kyung, "Lee Whee Kyung, is workplace a playground? Are you here to play?" and Lee Whee Kyung said, "My work is done" as he was happy-go-lucky.
At this, Diretor Yoo said, "If your upperclassman's work isn't done, your work isn't done either. I knew something was wrong when a rookie would put pictures of celebrities on their computer" and scolded him.
At this, Lee Whee Kyung whispered in his ear that Chun Song Yi was his girlfriend and Director Yoo said, "Shut up! If Chun Song Yi is your girlfriend, Kim Nam Joo is my wife!" and shouted. People at our company put pictures of our family members on the background of our computer desktop nd work like crazy" as he nagged.
Afterwards, Lee Whee Kyung put a picture of his father in a family portrait on his desktop and Director Yoo was surprised. He was the son of the CEO.
