Rak Nai Roi Luang

Rumrada (Anna Glucks) is a young woman trying to uncover her past after being adopted by Sasis (Natthanun Khunwat), the patriarch of the Asanamontri family and owner of the country's largest sugar business. She was taken into the Asanamontri household as a "daughter." Rumrada has always known she was an orphan whose parents died in a fire over a decade ago, an event that caused her to lose parts of her memory. Sasis provided her with shelter, food, and education under the care of Mother Chuen (Sawanee Utoomma), a former housekeeper of the Asanamontri family, until she graduated and became a freelance photographer.
Through her work as a photographer, she meets two men. The first is Nasit Asanamontri (Artit Tangwiboonpanit), Sasis's only son, who saved her from criminals while she was working. Nasit does not get along with his father because he believes Sasis caused his mother, Naree (Mantana Himatongkam), to suffer through dishonesty and infidelity. Naree and Sasis are separated but refuse to divorce due to unsettled inheritance and asset issues. Naree tries to push Nasit to take over the Asanamontri company, a plan that Sasis and Chidchan (Marisa Anita), his close secretary, seem to be aware of.
The second man is Kanut Taosatranon (Pongsakorn Tosuwann), a warm-hearted plant shop owner who saved Rumrada from being hit by a car. Later, Kanut comes to work at the Asanamontri company through the invitation of Khanittha (Chertinnara Pongpeeradej), Nasit's secretary.
When Rumrada decides to seek the truth about her past—whether her parents' deaths were an accident or murder, and who might be behind it—she discovers irregularities in both the stories she was told and her own fading memories. The only person who seems able to help her is Chooklin (Sarocha Watitapan), the head housekeeper of Asanamontri and a close friend of Phad (Chatchadaporn Thananta), Rumrada’s mother.
Importantly, Chooklin knows the details of the past event where Sasis suffered memory loss from an accident and was under the care of Rong (Panu Suwanno), Rumrada’s father. Chooklin recounts that Phad and Rong died in the flames, while Rumrada was severely injured and burned. A single bracelet she wore was the only thing that confirmed her identity.
However, the more she investigates, the more anomalies she finds regarding the past. This involves her uncle Ram (Warawut Brown), her aunt-in-law Ngoh (Watsaporn Wattanakoon), her cousin Rujee, and Yom, a garden worker. Additionally, she is haunted by a "Ghost Child" in her nightmares from childhood to the present.
As her memories begin to piece together and the truth becomes clear, Rumrada is shocked by the revelations that lead her to the answer: Who killed her parents, and who is behind the covered-up murder?
