Gym Redemption: Ethan's Revenge

Ethan, a mixed-race orphan, does grunt work at the Blake family gym and suffers long-term humiliation from Derek, the second son of the family. Derek stops at nothing to fight for the family fortune, even murdering his elder brother.

Ethan befriends investor Scarlett, Derek's wife Chloe, and others, collecting all the evidence of Derek hiring killers and seizing the family property, fighting back step by step. He secures investment, exposes all the conspiracies, topples Derek, and finally takes control of the Blake Group, staying with Chloe who is pregnant with his child, achieving a double reversal in career and life.
