Dok Oor Sai Kwan

Khom, a charming young man, must disguise himself as a servant to infiltrate Baan Sak (Sak House) and uncover the truth. He is aided by Sai Kwan, a wealthy heiress who ran away from her own wedding, posing as his cook and fake wife. Their chaotic, hilarious, and perilous mission begins! They must conceal their identities to discover the dark secrets of Baan Sak, but can they conceal the overflowing love they feel for each other?
Sai Kwan (Yardthip Rajpal), the cherished only daughter of Madam Saijit, a wealthy socialite, flees her wedding in disarray to escape a forced marriage. In a stroke of fate, she hides in the car of a stranger, Khompetch or Khom (Kiatkamol Lata). Khom is on the most important mission of his life: to uncover the truth about his birth! However, his plans go awry when he encounters Sai Kwan, a stranger being chased and carrying expensive valuables. Convinced she is a thief, Khom’s troubles multiply when Art-Ong, a mysterious hitman in a black sedan, begins stalking and attacking him. Khom is forced into an adventure with this "thief" he initially dislikes. But after surviving life-and-death situations together, their animosity turns into a necessary partnership.
Non and Ngam, a married couple and Khom’s close friends, deliver shocking news. The original plan was for Khom to work as a driver at Baan Sak, the house his father Sak (from whom he was separated as a child) promised him in a letter. However, Sak’s younger brother Suban and nephew Singha deny Khom is mentioned in the will. Khom needs to investigate, but Baan Sak changes its hiring policy, now seeking a married couple as servants. Khom begs Sai Kwan to pose as his fake wife.
Sai Kwan, relentlessly pursued by her mother, agrees, seeing this disguise as her best option. Non and Ngam transform the high-society pair into low-class servants. Khom becomes Nai Wai, and Sai Kwan becomes Dok Oor. No one suspects Sai Kwan’s true identity. They manage to pass the inspection of Khun Niam, the strict head housekeeper, and are accepted into the household.
Baan Sak is a grand mansion with questionable ownership. Besides Suban and Singha, there is Sita, Singha's fashionable younger sister who constantly argues with him because Suban spoils her. Unbeknownst to Suban, his precious daughter has been secretly involved with Chat, Singha's bodyguard, for two years, hiding their relationship due to his lower status.
Getting into the house is just the first step. Besides searching for the will, Khom and Sai Kwan are exhausted by hard labor and the challenge of maintaining their charade amidst a household of gossip-loving servants. They deal with the strict Niam, Juan (a maid who has a crush on Khom and watches the fake couple closely), and Pud (an adorable but nosy young girl). They nearly get caught several times. To make matters worse, the lecherous Suban constantly tries to force himself on Sai Kwan, forcing "Nai Wai" to fiercely protect his "wife."
Meanwhile, Prince Pongnarin, the abandoned groom, faces a crisis. The humiliating truth is he agreed to the marriage to pay off his late parents' debts with money from Saijit. Saijit, a wealthy widow and former beauty queen constantly gossiped about for her background, wants to improve her image by marrying into aristocracy. She threatens Pongnarin with the debt, forcing him and his aide Mieng to join her and Fad (Saijit's aide and Sai Kwan's nanny) in hunting down Sai Kwan.
Kongkaew, Khom’s girlfriend who initially opposed his mission, realizes her selfishness. She asks Pee, her ex-boyfriend and owner of Peeraphan Resort, for help finding Khom, as his resort is near Baan Sak. Pee agrees after much persuasion. However, chaos ensues when Pee’s tomboy sister, Pintu, gets involved with Prince Pongnarin, who becomes a guest at the resort. While Pee succumbs to Kongkaew’s charms, Pintu falls for Pongnarin’s, agreeing to help him find his "misunderstood" runaway bride.
Khom and Sai Kwan get their first lead on the will from Nai Mak, Sak’s old confidant now in a mental asylum. Mak confirms the will exists but doesn't know where it is. Khom decides to seduce Sita to get information, which affects his and Sai Kwan’s feelings. Sai Kwan gets jealous, and when Kongkaew manages to befriend the household, she too tries to get close to Khom. In retaliation, Sai Kwan flirts with Singha to get information quickly. Khom, unable to bear his jealousy, constantly picks fights with her, eventually admitting to himself that he has fallen completely in love with his fake wife.
Prince Pongnarin tricks Pintu into searching for Sai Kwan, but his deception is revealed. Pintu punches him and lectures him on using others to solve his problems. When Saijit finds Sai Kwan, Pintu helps her escape again! This sparks a war between Saijit and Pintu. Pintu kidnaps Pongnarin to use as leverage against Saijit. During his captivity, Pintu teaches the spoiled prince honesty and self-reliance, and their feelings for each other grow.
Although Khom confesses his love, Sai Kwan doesn't believe him, thinking it's just a fleeting emotion from their proximity. Meanwhile, Suban plans to invest Sak's massive fortune in his own name. Khom risks everything to find the will quickly, using himself as bait at Suban’s company. Singha sends Art-Ong to kill him. During the chase and attempts to destroy evidence, Sai Kwan, Non, and Ngam gather proof that Singha and Suban forged the will and were involved in Sak’s death. Singha realizes Khom is the man he hired Art-Ong to kill and is now in his house!
Singha kidnaps Sai Kwan to bargain with Khom. Saijit, realizing her daughter is in danger, regrets her controlling ways. Pongnarin, Pintu, Kongkaew, and Pee all join the rescue. Khom turns the tables on Singha. Seeing the sacrifices Khom and Sai Kwan make for each other, Kongkaew finally gives up on Khom.
The real will is revealed. Singha goes to prison. Suban suffers a stroke and becomes paralyzed for life. Chat, also imprisoned, asks Khom to spare Sita, as she was innocent. Khom gives Sita a share of the inheritance to start a new life. Saijit reconciles with Sai Kwan and promises to stop controlling her. It is revealed that "Dok Oor" is actually a billionaire heiress!
Khom and Kongkaew clear the air; she decides to give Pee, who has always stood by her, a chance. Saijit lends money to Prince Pongnarin to start a business, with Pintu as his advisor.
In the end, three couples—Khom & Sai Kwan, Prince Pongnarin & Pintu, and Pee & Kongkaew—find happiness and love after all their struggles.
