When u were a kid u had a bsf, Ace... he then flew to another and never saw him again. Before he went u gave him a matching necklace... years later U were in class and the teacher introduced the class to the new student and he sat next to u

"Nice necklace" he said looking at ur necklace.U looked at his necklace and it had the same matching necklace u gave to ur childhood bsf.U then connected the necklaces together and they fit perfectly

"Ace?!" u said looking at him in shock
