My sister, whom I raised, has turned evil after faking her death for three years.

Su Qing was never given a choice—only a transaction. Desperately ill and with nothing left to lose, she accepted a singular, binding contract: raise a child in exchange for her own survival. For years, she poured everything into nurturing Jiang Ran, watching the quiet, fragile boy grow under her care. Their arrangement was supposed to be simple, clinical, and temporary. But nothing about what came next was ever simple. When her contract abruptly ended and she disappeared from his life, Su Qing believed she had closed that chapter for good. Three years later, fate cruelly reunites them—but the gentle, obedient boy she once knew is gone. In his place stands a man consumed by a cold, obsessive hunger, his eyes dark with something far more dangerous than nostalgia. As Jiang Ran corners her with a possessiveness that borders on madness, Su Qing realizes too late that some debts can never be repaid. And some bonds, once severed, only grow sharper with time.
