زيرو جيون

Kim Villan is an 18-year-old teenager in her senior year of high school. She has long black hair that matches her wide eyes, childish features, and glowing white skin. Her parents died in a fire, so she moved in with her uncle and his wife. She suffered through poverty with them, as well as her uncle's violence toward her and his wife because they wouldn't give him money for gambling.

Driven by desperation, Villan hacked into Jeon Jungkook's bank account and stole a million dollars. She was overjoyed by the news, but by evening, the police arrived searching for her. She leaped out of her bedroom window and began to run, having discovered that Jungkook is a 30-year-old Yakuza mafia boss who kills anyone who steals from him.

As she was running for her life, she suddenly collided with a tall man wearing a formal black suit topped with a long black coat. She had no idea that he was Jungkook, known as Zero.
