The story of Shen Qingli, a messenger from the spiritual world who has been wandering in the human world for nearly a thousand years. Carrying the countdown curse of "burning her body in flames", she must find the most benevolent soul as her successor in the modern city. Ostensibly a primary school teacher, she discovers two special students in her class - Zhou Mingxuan, a seemingly domineering rich man, and Lin Xiao, a flawless orphan.
When Lin Xiao carefully designed to frame Zhou Mingxuan, Shen Qingli was keenly aware of the disturbing familiarity exuding from this child. With repeated temptations and crises, she is pulled into the whirlpool of thousands of years of memories: from the betrayal of her first love in the late Ming Dynasty, to the use of merchant families in the Qing Dynasty, to the betrayal of her best friends during the Republic of China - the source of all tragedies is actually the same soul's careful calculation spanning thousands of years.
The modern campus has become the ultimate battlefield. When Lin Xiao set a fatal trap, Zhou Mingxuan showed his true nature of goodness at the critical moment of life and death. The mystery that has lasted for thousands of years has finally been revealed: true kindness is not a perfect appearance, but the true heart that can still persist through filth. After Shen Qingli ended this thousand-year entanglement, she finally handed over her mission to someone truly worthy of her trust. She was reborn and experienced the preciousness of human fireworks in her limited life.
