"You gave me your chance of rebirth, so in this life, let me save you." Intern cat demon Shi Miao transmigrated into a book, tasked with saving the pitiful, strong, and tragic villain youth Jiang Yingxu. She turned into a calico cat to guard him in secret, and also transformed into a stunning girl to walk with him through his lowest points. Together, the two tore apart family conspiracies. Just as Jiang Yingxu passionately proposed at the lantern festival, Shi Miao turned back into her original form due to supernatural power exhaustion. Jiang Yingxu broke into the system space for love, and the dusty truth of the past life surfaced—it turned out this was not accidental transmigration, but his premeditation across life and death. When the timeline resets and memories are cleared, the destined two will eventually embrace again in a new world.
