Luk is the only son of His Highness Naruenat and Lady Sri. His father brought Kae, another one of his wives, to live in the house. He now has a little brother named Peemarn. Soon after his father’s death, Peemarn was sent to study abroad with Luk. Then Lady Sri became severely ill. Before she died, she entrusted everything to Kae. After finishing his education, Luk takes over the family business. Although he is successful in business, he is often criticized for his social behavior. The complaints went to Kae who, unsuccessfully, tried to find a good woman that is suitable to marry Luk. She then turns her attention to Peemarn instead. However, he already had a woman he loved so he refused. Therefore, she asked Luk for help. Luk met Rojarate, who was the love of Peemarn, and told her he would pay her 10 million baht to break up with him. He also signed a marriage license with her and planned to divorce her once he is certain that Peemarn would marry Nutta, the woman his mother chose.
