Rak Khong Nai Dokmai

Ratchaphruek (nicknamed Nai Dokmai) is the handsome owner of the "Mr. Flower" floral shop chain. While inspecting one of his branches, he encounters Phuangchomphu, a woman whose beauty leaves a lasting impression on him. Later, at a party, Phuangchomphu mistakenly assumes Ratchaphruek is just a delivery boy for Mr. Flower. She scolds him for a late delivery and even asks him to pass her complaints along to the manager. Ratchaphruek simply smiles and accepts her criticism without revealing his true identity.

The Undercover Romance

Ratchaphruek decides to pursue Phuangchomphu, but he intentionally hides his wealthy status. He wants to win her heart as "Nai Dokmai," the simple delivery man she believes him to be, to prove that she loves him for who he is and not for his business empire.
However, a major obstacle stands in his way: Lieutenant Komut. Komut is an army officer and the only son of General Kanlaphaphruek and Khunying Kradanga. He is also actively courting Phuangchomphu, backed by the heavy influence of her father, Colonel Phu Nayphon. The Colonel is desperate for a promotion to General—a rank he has missed out on for years despite graduating in the same class as his peers—and he hopes to use Komut’s father's connections to finally secure the position.

Battles of the Heart

Despite the odds, Nai Dokmai doesn't give up. He manages to get close to Phuangchomphu by winning over her mother, Khun Phlapphueng. On the other hand, Colonel Phu Nayphon takes an immediate dislike to the "flower boy."
When it becomes clear that Phuangchomphu is actually developing feelings for Nai Dokmai, her father refuses to accept it. The Colonel and his preferred suitor, Komut, team up to find a way to get Nai Dokmai out of the picture for good. How will the love story of "Nai Dokmai" end? You'll have to follow and cheer him on in the drama Rak Khong Nai Dokmai.
