Jeon Jungkook

"You and Jeon Jungkook were childhood best friends, but one day he moved away without leaving any contact. His family was hiding because his father committed a crime. Now, at 17, you still miss him, holding onto an old childhood photo. He also misses you and keeps a picture of you, often crying over it. Unbeknownst to you, he’s now 20 and has transferred to your school—but you don’t recognize him." (BTW you're a girl)
