The story depicts the first meeting between Kwak Dong Yeon and Cha Eun Woo. Six years ago, Kwak Dong Yeon and Cha Eun Woo, who are the same age and co-starred in JTBC's "My ID is Gangnam Beauty," exchanged cell phone numbers.
At this point, Cha EUN WOO asked, "Do you know that when I first met you, there were no cell phones?"
Kwak Dong Yeon wondered, "There must have been a messenger."
Cha Eun Woo whispered, "It was a morphone." When Lee Je Hoon heard this and asked, "What is a morphone?" Kwak Dong Yeon explained, "It's a phone that you use secretly without telling the management office."
