Boon, a struggling hair stylist, flees to Chiang Mai after losing her job and discovering her boyfriend’s betrayal. While at a hot spring, she nearly drowns and is mysteriously saved. When she awakens, she finds herself in the body of Princess Fongnuan, a sickly noblewoman in the ancient Lanna Kingdom. Adapting to her new life, Boon faces the challenges of survival and love, encountering kind Chao Saen Thep, her sister's fiancé, and the stern Chao Mueang Fah. Her unconventional thoughts captivate those around her, bringing a fresh perspective to the kingdom's old ways.
