Harit Rangsiman is devastated by the death of his younger brother, Harin. Driven by grief and a desire for revenge, he sets out to capture the culprit—but unknowingly kidnaps the wrong person: Soraya.
Soraya is forced to submit to Harit’s harsh treatment. He abuses and orders her around like a servant, while his mute companion keeps watch to prevent her escape. One day, while away on business, Harit meets Sansanee—the real person responsible for harming his brother. When she shows him her ID card, he realizes the truth: he has taken the wrong person all along.
Meanwhile, Sansanee, who already has a boyfriend named Thawatchai, begins to distance herself from him after developing feelings for Harit. Feeling guilty, Harit and his companion finally release Soraya and give her a pearl necklace as compensation.
Sansanee later borrows the necklace from Soraya. When Harit sees Sansanee wearing it, he asks where she got it. She tells him she borrowed it from Soraya. Harit then offers to buy it for 100,000 baht, and Sansanee sells it without even consulting Soraya. When Soraya finds out, she is heartbroken over losing the necklace Harit gave her.
However, Harit secretly buys the necklace back and returns it to Soraya.
At the same time, Harit pretends to grow closer to Sansanee, causing her to fall for him even more. Soraya warns Sansanee to stay away from him, but Sansanee accuses Soraya of liking Harit herself—which Soraya denies.
One day, Harit formally asks for Soraya’s hand in marriage from Sansanee’s parents, Sukrit and Saisamorn. Thawatchai, believing Harit has betrayed him, attacks him. Harit declares that he loves only Soraya.
Sansanee initially assumes Harit is proposing to her and calls Soraya to mock her—but when she learns the truth, she becomes furious.
In the end, Soraya begins to treat Harit like a servant in return, and the two live happily together.
