After Transmigrating Into the Book, I Raised the Sickly Side Male Character to Be the Yandere

In a fantasy romance set in ancient times, the story features system-based transmigration with sweet yet tragic elements. The protagonist, Jiang Niannian, is fond of the beautiful yet tragic male supporting character named Yin Li, whose life is filled with misfortune. He is unloved, abandoned by the female lead, and meets a miserable end. Jiang Niannian declares, “Let go of my poor cub; I’ll take care of him!” She then transmigrates into the story as Yin Li’s personal maid, binding herself to the sickly male supporting character rescue system. Determined, she follows her own unique philosophy of “loving and doting on her beloved baby.” But why does this precious good cub, whom she’s been nurturing with so much care, end up turning dark and twisted?
