On a snowy night in Jiangcheng, Iris Yates, the owner of a noodle shop, encounters Alistair Shaw, who is covered in blood and holding a baby. An embroidered plum handkerchief and a white jade pendant set the stage for the fate that ties them together. To overturn the wrongful conviction of her imprisoned parents, Iris, who is still breastfeeding, enters the top-tier wealthy The Shaw Estate to become the exclusive wet nurse of the Little Master. She initially expects the hardest part to be navigating the estate's strict rules and gossip, but what truly disorients her is the legendary cold, sharp, and long-mute The Patriarch of the estate — the same man she saved that snowy night. Everyone in The Shaw Estate knows Alistair is indifferent to women, but he grows deeply attached to Iris, to the point of obsession, as the old poem goes: "I know it is not snow, for the faint fragrance comes from the plum blossoms." Dark undercurrents and dangers lurk within the estate, but Alistair always stands behind her to protect her, using sign language to tell her: "I trust you." Until a paternity test reveals all the truth: the one who shared a night of passion with her years ago was Alistair, and the child she thought was stolen and dead never died. The encounter on that snowy night was never an accident, but a preordained twist of fate. On the day their new child is born, Alistair, who has been trapped by Aphasia for thirty years, speaks his first words in his life: "Iris."
