Phu later returned to Rayong to visit his father, and wrote a poem about the journey called "Nirat Mueang Klaeng" which became one of his most famous poems. He wrote the epic poem for his fiancée, Chan. After he returned to the palace in Bangkok he married Chan, and they had a son named Phat. It was at this time that King Rama II appointed him court poet. However, the couple were not married long, divorcing after Phu had an affair with another woman. This was the first of many marriages ending in divorce, although he later professed that the wife he had loved the most was Chan. Phu became an alcoholic, and, around 1821, was jailed after a fight.
