Because of her mother's promise, Kulthida — a brilliant Thai-American with a high IQ — is sent to Thailand for six months to work as a maid for Rawit, a grieving widower, and care for his young son, Ramil. Her dream of becoming the manager of Made to Your Home depends on her success.

But her job is more than cleaning and caretaking. Kulthida must also protect the Phiphatphong family's assets, all while navigating a household torn by rivalry and greed. Between emotional wounds and family feuds, her mission becomes more complicated than she ever imagined.
