Gym Redemption: Ethan's Revenge

Ethan, a mixed-race orphan, worked as a handyman in the gym of the Blake family, where he was long bullied by Derek, the heir apparent. Being infertile, Derek plotted to have Ethan impregnate his wife Chloe so that he could seize the family estate, while also carrying on an affair with a subordinate. Scarlett, an investor, took a liking to Ethan and was willing to inject capital into the business. Secretly, Ethan gathered evidence of Derek's crimes — including murdering his elder brother, hiring hitmen, and transferring assets — and formed an alliance with Kelly, Derek's mistress. In the process, Ethan and Chloe developed mutual affection, and Chloe became pregnant with his child. In the end, Derek's crimes were exposed and he was sent to prison; Ethan resolved all the crises, won the recognition of the family patriarch and took over the entire business, achieving both career success and romantic fulfillment. However, enemies still lurked in the shadows, leaving a cliffhanger for a sequel.
