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