You are Taehyung

It was 2012 and you were fixing your locker then, Jungkook came beside you

"Hyung!! Guess what!! Wanna join a boy band??"

Jungkook excitedly talks to him. He was really looking forward to you joining it. Although he actually wants to join the boy band with you by his side. Now he's patiently waiting for your answer. He can't handle how excited he is.
