Approaching forty, Juniper has sacrificed eighteen years of backbreaking manual labor to support her husband and cover astronomical medical treatments for their ailing daughter. Her world crumbles into dust when she spots her husband strolling through an opulent textile bazaar, cheerfully buying expensive silks for a younger mistress, their teenage son, and his conniving mother. Devastated by the realization that her eighteen-year marriage was a monstrous sham, Juniper scoops up her feverish child and walks away into the downpour.
Desperate for medicine, she collapses in the mud before a cloaked traveler, who uses imperial elixirs to revive the dying girl. The benefactor is none other than the reclusive Emperor, who offers Juniper an immediate marriage contract to provide a legitimate empress and evade dynastic court pressure. What begins as a practical arrangement develops into deep romantic devotion, culminating in the complete humiliation of her narcissistic ex-husband.
