Shen Xiaoyi, the Flower Goddess of the Heavenly Realm, is banished to the mortal world for a mistake. To return to her rightful place, she must recover her natal flower bone and guide three people to fulfillment. Pretending to be weak while concealing her immortal powers, she secretly protects her family. The destitute young man she saves turns out to be the reincarnation of her own flower bone. Three years later, he becomes a powerful regent and demands to marry her. Together, the couple humiliates their enemies and punishes the wicked while fighting corrupt ministers who conspire with demonic creatures to usurp the throne. But the laws of heaven are merciless. To save the male lead from death, the female lead exhausts her immortal essence and leaves her flower bone to him. She returns alone to the Heavenly Realm to face punishment, leaving him behind in the mortal world to wait beneath the peach tree that never withers.
