"Agent PB, youve been trained for any circumstances. You are the best and the most proper age and visual to handle this matter. But, for mission safety, you better lessen your skill, you shouldnt too much noticeable by public. Your visual is more than enough, if you show your maximum skill too, Im worried you will gain too much public attention, it will causing troubled for yourself, but still you have to be able adjusting with the group. Your new name is Kim Sojung. Your stage name will be Sowon, but you might be not used it yet untill your debut. I already set everything there wont be any problem with the agency. So pack your stuff now, Youll start tomorrow." That charismatic man give an order while hand a folder contain of a brief papers, documents and new ID-card named Kim Sojung.She nod her head firmly, take the folder then leave that room. ForewordThis just my imagination, what if Sowon actually a spy who join GFriend for secret mission.The agent name PB. I get that from variety show New Yang Nam Show when GFriend been a guest, Sowon said as trainee she made of alias name PB that stand for Perfect and Beautiful. Pretty much confident, huh?!^^ This is the begining story, also check on the sequel of Spy Unnie, thanks!^^
