Firefighting hero Cui Ying fell into a coma after sustaining severe injuries while saving lives. Her ex-boyfriend, Gu Jun, devoted himself entirely to her medical care, yet her aunt's family pressured her mother to give up hope. Her soul having left her body, she struck a pact with the God of Death: she would undergo seven reincarnations as various animals; if her mother recognized her in each life, she would be granted a rebirth. Her mother recognized her through the first six incarnations, but in the seventh—when she appeared as a little yellow dog—her mother failed to recognize her. Just as despair set in, the God of Death made an exception: it turned out the entire ordeal had been a dream. Upon waking, Cui Ying not only received a marriage proposal from Gu Jun but was also awarded the highest honor in the firefighting service.
