A tale of the underworld in the 1990s. A group of unusual people enter the underworld amid extraordinary circumstances, following the rise of their gang from its formation to its growth and eventual destruction. The underworld is an unfathomable abyss, and once a person steps into it, they are no longer in control of their own fate. Only they can understand what it is like. Take a closer look at the people in this story. Some lose many things while pursuing status and profit, becoming unscrupulous before ultimately meeting a dead end. Some are unruly and violent, fleeing for their lives until they are finally harshly punished by the law. Others are left disabled, or even lose their lives, while trying to help their gang grow, and are eventually forgotten by society. There are also those who never forget their original aspirations, yet reality leaves them no control over their own lives. The right path is to turn back before it's too late. Looking closely at these tales of the underworld and savoring them in retrospect, one realizes that there is no right or wrong in the underworld. Perhaps choosing this path in the first place was itself a mistake.
