Rabiang Rak

Nakaraj Palace, home to Mom Yubol, welcomes three new members: the daughters of Tan Chai Lek—M.L. Tevika, M.L. Thuwadara, and M.L. Thawicha. However, Mom Yubol does not show them much affection, as she already has a favorite granddaughter, M.R.W. Ratchaneewipha (the daughter of M.C. Phrotphisut and M.R.W. Yuwadee).
Ratchaneewipha is deeply in love with the handsome royal M.C. Danainaruemit, ignoring the advances of a foreign painter named Jonson. To help the three sisters, Lord Phrot invites Danai and Mom Yubol to dinner and introduces Tevika and Thuwadara. He advocates for Thuwadara’s education, forcing Mom Yubol to allow her to study. Meanwhile, Tevika is approached by Jonson to be his muse and art model.
Jealousy and Rivalry
Tensions rise when Thuwadara passes her university entrance exams while Ratchaneewipha fails. Ratchaneewipha tries to win Lord Danai's heart by changing her style to be more provocative, but she is crushed to learn he does not love her. Seeking comfort, she turns back to Jonson, only to find him infatuated with Tevika. Driven by spite and a desire to win, Ratchaneewipha begins an affair with Jonson.
Thuwadara enters the university where Lord Danai is a professor. Mom Yubol warns her that Danai and Ratchaneewipha are already intended for each other. Around this time, Lord Danai’s friend Wiphat, a divorcee with a daughter named Pharanee (nicknamed Luk Kai) who suffers from polio, seeks a nanny. Thawicha refuses the job but eventually becomes a famous fashion model.
Accidents and Arrangements
When Lord Danai drives Thuwadara back to the palace, an argument about his supposed engagement to Ratchaneewipha leads to a car accident. To protect Thuwadara’s reputation from the malicious gossip of Yuwadee and Ratchaneewipha, Lord Danai steps up and agrees to marry Thuwadara.
Devastated, Ratchaneewipha spirals into a lifestyle of drinking and late-night partying, deepening her relationship with Jonson. Meanwhile, Thawicha’s path crosses with Wiphat when she saves Luk Kai from an accident. The little girl becomes a "Little Cupid," trying to set up Thawicha and her father. Their love begins to bloom, but the return of Wiphat’s ex-wife, Uma, temporarily halts the relationship. Thawicha leaves for a modeling job in Hong Kong, but Wiphat rejects Uma and follows Thawicha abroad.
The Resolution
Tevika announces her plans to marry Jonson, which causes Ratchaneewipha to collapse. A doctor reveals that Ratchaneewipha is pregnant, though she refuses to name the father. Mom Yubol is heartbroken and withdraws from society. However, Thuwadara’s genuine care eventually wins over Mom Yubol, who finally accepts her as a beloved granddaughter and supports her marriage to Lord Danai.
The truth eventually comes out: Ratchaneewipha tries to take her own life, and everyone learns that Jonson is the father of her child. Thuwadara finds a solution—she agrees to marry Lord Danai and proposes that Ratchaneewipha go abroad to study and give birth. Thuwadara and Lord Danai will then adopt the child as their own to save the family’s honor.
