Modern medical doctor Tang Zhujun time-travels, becoming a notorious, unwed mother and infatuated fool. The original host drugged and entangled Prince Jin, leaving behind a mess of trouble. Relying on her medical skills to make a living and support her family, she tears apart vampiric grandmothers, schemers like Ruan Anruo, and other extremes, rescues the noblewoman Meng Yulan from desperate straits, and supports each other with her older brother Tang Baixin. Prince Jin initially rejects and loests her, but gradually falls in love, while an imperial decree of marriage from the Emperor presses down. Two adorable children, Linlin and Yanran, accompany her on both sides as court conspiracies and secrets of birth successively erupt. Unwilling to become a pawn of imperial power, Tang Zhujun joins hands with relatives and friends to break the deadlock, shakes off feudal shackles, and lives out a clear-headed and self-reliant life.
