"You Who is From the Stars" Kim Soo Hyun found out Jun Ji Hyun's identity but didn't believe it.
On the 3rd episode of SBS Wednesday/Thursday "You Who Is From the Stars" broadcast on December 25th, Chun Song Yi (played by Jun Ji Hyun) had a appendectomy and was admitted to the hospital.
On this day, Do Min Joon asked Chun Song Yi about her identity and Chun Song Yi said, "What do you mean who am I? I'm Chun Song Yi" as she was flabbergasted.
Min Joon said, "Yes, it's Chun Song Yi. It can't be that woman." And mumbled Song Yi said, "Who is the woman? Does she look like me? I guess these days with plastic surgery, everyone wants to Chun Song Yi. But you can't follow the original" and was arrogant.
At that time, Min Joon saw the shoes that Chun Song Yi was wearing and looked at the shoes and at the same time, witnessed a woman wearing the same shoes jumped down.
Min Joon asked about the owner of the shoes, Song Yi said, "We only have one pair left. I'm not a person that can wear just anything" and showed off the shoes.
