Fai Nai Wayu

Thara leaves her love, Dr. Phupha, to marry Chatree Thanakul—even though she knows he already has a wife, Duangdao, and a son, Wayu. Shortly after Thara gives birth to Kraikoon, Duangdao dies, leaving Wayu in Thara’s care. Although she raises him with love and attention, Wayu always feels he is loved less than his younger brother Kraikoon, who is weak and often ill.
Wayu grows up to manage the Thanakul family business, turning it into one of the country’s leading companies, while Kraikoon wastes his time living a carefree and aimless life. Kraikoon then hires Lawaeng to pretend to be his girlfriend as part of a plan to eliminate Wayu.
During Thara’s birthday party, Wayu and Kraikoon have a heated argument in front of the guests. Wayu retreats to his room, and upon waking, finds Kraikoon pretending to be dead. Lawaeng arrives, follows the plan, accuses Wayu of murder, and urges him to flee to Wayukul Farm—hoping that Usaren, her accomplice, will follow and kill him.
That night, a storm forces Wayu to take shelter at Sai Nam Resort, owned by Dr. Phupha, the uncle of Salil (also known as Lukwa), who is nursing a broken heart. Overcome with guilt and mental turmoil, Wayu isolates himself, despite Lukwa’s attempts to help him.
Meanwhile, Kraikoon appears at Khwan Kaew Farm, owned by Nuan Khwan and her younger brother Thaklaew, pretending to be Wayu Thanakul. He deceives Nuan Khwan into selling the farm to Kasit, a scheming businessman. However, Nuan Khwan’s strength and determination begin to attract Kraikoon, while at the same time Wayu slowly opens his heart to Lukwa.
At a Saturday party at the resort, Kraikoon encounters Wayu, who believes he is being haunted by his brother’s ghost. Later, at Khwan Kaew Farm, Wayu finally meets Kraikoon in person, and the truth begins to unfold. Nuan Khwan is heartbroken by Kraikoon’s deception. Kraikoon shifts all the blame onto Lawaeng and Usaren. Devastated that Kraikoon does not love her, Lawaeng reveals the entire truth to Wayu.
Thara, the mastermind behind everything, shoots both Lawaeng and Usaren for betraying her and blames Kraikoon for ruining the plan. This leaves Kraikoon deeply shaken.
With everything exposed, what fate awaits Thara and Kraikoon?
