Thitphati Techpipat, a charming playboy and successful businessman, is used to having women fall for him—until his secretary, Jitsagao, becomes the first to reject him. For someone as proud as Thitphati, it’s a blow to his ego, and he sets out to win her heart at all costs.

But Jitsagao has a painful secret: she’s connected to the accident that left Thitphati’s sister, Khaloonji, paralyzed. Guilt keeps her at a distance, even as her feelings grow. As Thitphati pursues her with determination, unaware of the truth, a battle begins—between guilt and desire, pride and love.
