"No one can belittle us if we don’t belittle ourselves." These words from her grandmother have stayed with Plubpla (Mukda Narinrak), a beautiful 23-year-old woman, all her life. No matter how hard life gets, she firmly refuses to sacrifice her dignity for money.

To pay for her younger brother Tong's (Natthaphat Jiraphawasuthi) tuition fees, Plubpla takes on a job as a promotional model at a luxury car launch event, arranged by Madam Chacha (Suphattharaporn Kasikam). During the event, she approaches Pheem Phattharatrakul (Euro Yotsawat), a young and successful businessman, heir to PP World, who has a deep-seated disdain for women who use their beauty to get ahead—stemming from childhood trauma. His mother, Maneewan (Kotchakon Nimakorn), abandoned the family after being heartbroken over his father, Phuchong (Phutharit Prombandal), impregnating Supang (Passorn Boonyakiart), a woman from a bar and bringing her into their home. As a result, Pheem sees all women in Plubpla’s profession as gold diggers.

However, Plubpla's persistence and unique sales skills unexpectedly impress him, leading him to purchase the car she’s promoting. Just as things seem to be going well, Weekit (Santirat Kulnopakiet), Pheem’s former best friend and business rival, offers to buy Plubpla’s "services," making Pheem misunderstand her intentions. Enraged, he lashes out at Plubpla, accusing her of selling herself. But Plubpla refuses to be looked down upon, publicly confronting him in front of reporters. Pheem is left humiliated.

Meanwhile, Phuchong, witnessing Plubpla’s fierce spirit, becomes intrigued by her, as she reminds him of his long-lost wife, Maneewan. He offers her a position at his company, which she accepts. Seeing his father take an interest in Plubpla, Pheem devises a plan to steal her away—partly to spite his father for what he did to his mother. He leaks information to Supang, fueling her desire to eliminate Plubpla. Despite multiple attempts by Supang to sabotage her, Pheem steps in to help each time.

Eventually, Pheem offers Plubpla a job as his secretary, under the pretense of protecting her from further trouble, but with the hidden agenda of making her fall for him. Concerned for her grandmother Yaa Thip (Panatda Komaratat) and her brother Tong’s safety, Plubpla agrees. However, her decision sparks the jealousy of Usa (Parita Chairak), the daughter of Thanathip (Chalermphon Phumpanwong) and Pheem’s close childhood friend, who has long harbored feelings for him.

As fate intertwines their lives further, Pheem’s company partners with Suthee (Paskorn Bunwornmathi), the husband of Tripradap (Amena Pinich), Plubpla’s elder sister. This forces Plubpla to work closely with Suthee, sparking Tribradap’s jealousy and prompting her to seek ways to get rid of Plubpla.

One fateful day, Pheem and Plubpla end up stranded together on a boat. This shared moment leads Pheem to see her in a new light, developing feelings of sympathy and admiration. As love gradually takes root, their emotions get the best of them, leading to an intimate encounter—one that neither of them realizes will alter their destinies forever.
