Once upon a time in the bustling city of Tokyo, there lived a young girl named Ji-Yeon. She was a Korean student who had recently moved to Japan and enrolled in a prestigious high school. Little did she know that her arrival would catch the attention of a powerful figure in the city's underworld, Asahi, the feared mafia president.

As Ji-Yeon continued her studies, she unknowingly became the object of Asahi's obsession. He would discreetly watch her from a distance.
