The Demon(2023)

The Demon is a Thai drama series about Sun, a man raised in poverty and resentment by his mother Srijan, who was cast out by the wealthy Phetchamekha family after bearing Sun as the mistress of the family heir. Srijan fills her son with lies and hatred, driving him to orchestrate an elaborate revenge against his half-brothers and father. Sun's plan is ruthless: seduce his half-brother Yang's girlfriend, expose his youngest brother Fu's sexuality, and destroy his father's reputation. But as Sun executes his calculated vengeance, he risks losing everything that matters—his humanity and Nam, the childhood sweetheart who still believes in him. Caught between his mother's ambitions and his own unraveling conscience, Sun discovers that revenge exacts a price far steeper than he imagined.
