M.R.W. Boworntep is a handsome high-society young man with countless romantic partners, yet every relationship inevitably ends in separation. Even his relationship with Yuwadee, a beautiful and popular socialite—whom his sister, M.R.W. Thepita, had tried to matchmake—fails, leaving many in their social circle puzzled.
The truth shocks everyone: Boworntep broke up with Yuwadee because he got another woman pregnant.
Meanwhile, Kingked, a young woman who has been unemployed for a year and is running out of money, decides to take a job at Dokrak Farm. To her surprise, the job requires her to pretend to be Boworntep’s wife in order to deceive his visiting sister. Though hesitant, she agrees after being offered a large sum of money and a promise that he will not take advantage of her. She needs the money to help her older sister, Kongkaew, start a bakery business.
As Kingked plays the role of Boworntep’s fake wife, Yuwadee arrives at the farm to reclaim Ray, but upon seeing Boworntep with Kingked, she believes Kingked is his real wife. This triggers her unstable mental state—she becomes obsessed with breaking them apart and shifts her attention back to Boworntep.
Yuwadee moves into the farm, openly claiming ownership over Boworntep and constantly picking fights with Kingked. Meanwhile, Boworntep grows closer to Kingked, refusing to let her keep her distance. Yuwadee’s jealousy escalates into violent behavior, even physically harming Kingked. Eventually, everyone agrees to seek psychiatric help for Yuwadee, though she refuses treatment.
At the same time, Ray and Thepita plan to build a resort and purchase part of the farm. During this period, Chokchai, Kingked’s ex-husband, reappears to reconcile with her. His presence creates tension, especially with Boworntep, as both men clash constantly. To drive Chokchai away, Boworntep fully embraces his role as Kingked’s husband.
Later, Kingked reveals the truth to Chokchai—that their marriage is fake—and admits she has fallen in love with someone else. Heartbroken, Chokchai wishes her happiness, unaware that Yuwadee has overheard everything.
Yuwadee then confronts Boworntep, declaring she knows the truth and is determined to marry him. She lures Kingked to a waterfall under false pretenses and threatens her, leaving her sick and alone. Boworntep cares for Kingked tenderly, deepening their bond.
In a fit of madness, Yuwadee later sneaks into Kingked’s room and shoots at her. Chokchai intervenes but is shot and severely injured. Boworntep rushes in, disarms Yuwadee, and sends everyone to the hospital. Yuwadee is institutionalized for her mental illness.
Kingked is only slightly injured, but Chokchai is critically wounded. Feeling guilty, Kingked stays by his side, which leads Boworntep to misunderstand her feelings. Their relationship fractures, and after a heated argument, Kingked decides to leave the farm and return to Bangkok.
Back in the city, she lives a sorrowful life, working in accounting to forget Boworntep. Eventually, Chokchai recovers and explains everything to Boworntep—that Kingked truly loves him but felt they were too different to be together.
Now, Boworntep must decide—will he fight for their love? And can a troublesome young master truly find happiness with a simple country girl?
