Jungkook was four years old when Jin became his stepbrother.
From that day on, Jin was his favorite person, his safe place, and the one person he never wanted to share. While everyone saw it as harmless childhood attachment, Jungkook's feelings only grew stronger as the years passed.
Some bonds are impossible to break. Some feelings are impossible to ignore. And for Jungkook, it had always been Jin.
