Jungkook writes of the pain of his soulmate, a person he's never met, into his songs.  He hates the way it feels, too personal and private, but at the same time he's curious.  There's no way anyone could be hurting so much inside and not break down.  Jungkook never wanted to feel another person's emotions but then he meets Taehyung and discovers he might just be okay with it after all.
