"Her journey here began in summer and ended in winter, yet she never met spring." — Yu Heng transmigrates into a novel and binds herself to a system. Her mission is to mistreat Xie Canglan, the sickly and dangerous villain, and then die at his hands so she can return home. She makes three attempts to get herself killed, each time courting death, only to be rescued by him all three times. What she doesn't know is that he has known from the very beginning that she came to take his life, yet he still repeatedly shields her from danger. On the day the immortal sects bring down their executioner's blades, Yu Heng throws herself forward and takes the fatal blow meant for him, dying in his arms. "He will find a way to reverse time and return to her side."
