Episode 6

Han Se-kyung’s best friend, Choi Ah-jung, accidentally sees her diary on how to get into Cheongdam-dong, and Han Se-kyung then confesses to her on what she is planning to do. Choi Ah-jung helps Han Se-kyung to look into Cha Seung-jo, at that time they know as Secretary Jin. Han Se-kyung got suspicious of Cha Seung-jo when Choi Ah-jung tells her that there is no one called Secretary Jin at all in Artemis. Han Se-kyung then asks Cha Seung-jo fiercely on whom he actually is. Under this moment of pressure, Cha Seung-jo makes a lame excuse that he is actually the President’s personal “shadow ninja”.
