The story
Quick answer: 7 episodes, English original audio, and episodes 1–7 play right here tonight.
Ethan is just a nobody working in an auto parts factory—bullied by his supervisor, humiliated by his boss, and cheated on by his ex-girlfriend in front of everyone. They all call him a loser. But Ethan never fights back, because his real identity is the president of the billion-dollar Sterling Group.
He went undercover to experience an ordinary life. Until his ex shows up to mock him, his boss forces him to drink piss, and a thug kidnaps his sister—Ethan has had enough.
