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