Phisuea Samut

One day, Phra Aphai Mani, a prince from the Rattana Kingdom, was sent to study abroad by his father, with the intention of having him ascend to the throne after his passing.

Aphai is a master of playing a magical flute called Pi (ปี่), which had the power to put people to sleep or even kill them.

Nang Phisuea Samudra was captivated by the beautiful music of the flute and decided to rise from the sea to find its source.

For eight years, Sin was kept isolated from the world until one day, Aphai revealed the truth about his mother to him and they devised a plan to escape.

The story ends with Aphai managing to escape and arriving on a shore, where he played his magic flute, breaking Phisuea Samudra's heart and killing her.
