Two teenagers who have been abandoned by the world are each other's only light. When the light is crushed by the evil of the world, the remaining people lose all tenderness, gamble with their lives, use their bodies as bait, and take fatal revenge to avenge all the sins hidden under the shiny skin.
The abyss represents the ruined native land, the indifferent secular world, and the dark humanity; looking back represents the obsession that persists in committing a crime until death. It is the only look back at Mika that he will never let go. It is also the fatal flaw that the murderer thought was perfect but ultimately exposed his flaw.
Two desperate teenagers in a remote mountain village hugged each other for warmth and depended on each other. They survived the desolation of youth without anyone to save them. They escaped together and wandered for three years. They took root at the bottom of the city and accepted that each other was their only relative and lover. Just the day after Mika came of age and the two were about to usher in a new life, a sudden sports car crash occurred. It seemed to be a speeding accident, but in fact it was a well-planned murder. The crime completely collapsed after confirming Maijia's body in the morgue, and the darkness that had been suppressed for several years completely exploded. He gave up the rest of his life and used his own life as a bet to lay a dragnet, step by step to dig into the truth and identify the real culprit. He used extreme methods to complete an abyss revenge with no consequences and shared death. The police simultaneously intervened in the investigation, forming a suspenseful line of solving the case in a two-way game.
Purpose: All members go into the abyss, solve crimes hard-core, and take revenge with high-burning madness
