Set in 1961, Saengrawi Raemsawang lived with Luang Lung Janthakorn until he turns twenty-one and is sent to live at Sitthikornkan Castle in Phra Nakhon. The castle is owned by Phraphloeng, currently living abroad. Heading the words of a sage, Phloeng's parents urge him back to Thailand. About to turn twenty-five, a prophecy requires him to soon find his soulmate to secure his safety; they may not be a woman, nor born in Phra Nakhon. Throughout his stay with Phloeng's family, Rawi is plagued by nightmares and haunted by a spirit. When he begins staying close to Phloeng, however, the spirit is quiet. It soon becomes clear that whatever is haunting the house is focused entirely on Rawi.
