Josh is your junior. You both didn't know each other but only know by name. He's a popular boy and you're a quiet and hard to get type of girl.

One day, your friends asked you if you had a boyfriend and you immediately tell them you got one. Once you saw Josh out of your class, you point at him and tell them that he's your boyfriend but they didn't trust you so you go and kiss him on the lips infront of your friends. “Sorry. Please pretend be my fake boyfriend for a few days.”
