(Beomgyu have 17 years old now)

Today in your class they went on a class trip, they went to visit busan, you were in a room with beomgyu, he was your best friend and you his best boy-friend, what a happiness, right?

You were talking to a friend while you were smiling into the phone, just because of something he sent you, Beomgyu was serious looking at you without saying anything, was he jealous?...
