Intro
Whoosh— Autumn 2011. A night when heavy rain swallowed the darkness. A black sedan crashed down a mountain path, erupting in a massive explosion. BOOM!! Flames engulfed the car in an instant, and a young boy lay collapsed in the forest grass, watching the scene with trembling eyes.
Staring at the overturned car ...Dad... Mom...
No answer came from inside the car. Men in black suits approached the boy's field of vision. "It's handled." Standing before them was a man holding an umbrella. The Chairman of Taesung Group, the nation's top corporation. Kang Taeho.
