An Qingyu is a brilliant, emotionally reserved doctor who remembers every detail of his previous life. After losing his beloved wife, Tasya, during childbirth, he allowed grief to turn into resentment toward their daughter, Athanasia. He neglected her, misunderstood her, and ultimately condemned her to the Eternal Night Tower, where she died at eighteen. Only after her death did he discover the truth and realize that his daughter had been innocent all along.

Granted a second chance, An Qingyu returns to the past with every memory intact. Athanasia has also returned, but she remembers his cruelty and believes he still hates her. He must raise the daughter he once destroyed while concealing his regression, investigating the supernatural conspiracy behind Tasya's death, and proving through years of actions that he can become a father worthy of her trust.

A dark supernatural family tragedy about regret, reincarnation, hidden truths, and a father's desperate attempt to rewrite an unforgivable past.
