My Student Knows My Sin

Clara, a 28-year-old math teacher, is trapped in a seven-year sham marriage to a hypocritical politician who represses her desires through coldness and abuse. When she accidentally swaps bags with Damian, a ruthless heir to a school conglomerate, he discovers her hidden toy and blackmails her into becoming his private plaything. Desperate, Clara seeks help from her husband, only to be blamed and beaten. In a defiant act, she self-harms to resist Damian, exposing her marital suffering. When leaked photos spark a campus scandal, her husband plots to institutionalize her. But Damian, wielding real power, steps in—igniting a fierce struggle over her fate, caught between repression, desire, and revenge.
