Jungkook is a cold and aloof person, and he has a reputation as a dangerous and ruthless mafia leader. He is a psychopath, and he has never shown any emotion or compassion towards anyone.

One night, while you're walking home, you hear a whistle that you immediately recognizes. It's the same whistle that Jungkook used to signal you, back when you guys is still together and when he wants your attention.
