Billionaire CEO Kael Kingsley grows distant from his wife Wren Sterling after misunderstanding that she has feelings for another man. When his ex-girlfriend Yuri Yale returns, claiming to suffer from leukemia, Kael spends increasing amounts of time caring for her out of a misplaced sense of responsibility, pushing Wren further away. Yuri repeatedly frames Wren, and Kael always believes her lies. Eventually, during a car crash orchestrated by Yuri, Kael abandons his injured wife and forces her to donate blood to Yuri. Wren is fatally wounded and dies full of resentment, her spirit lingering in the mortal world to witness everything. Six-year-old daughter Suri tries to wake her mother by braving the rain to ask her father for a Shell Wind Chime, only to be framed and abused by Yuri, even forced by her father to kneel before the "murderer" of her mother. At the height of despair, Wren's long-lost older brother Cheng Yan arrives, exposes the truth, and brings Wren's body alongside evidence of Yuri's crimes to Kael and Yuri's engagement banquet. The wedding turns into a funeral. When Kael discovers the truth that his wife has long been dead and he himself has tortured his own daughter, he falls into endless remorse. In the end, the truth comes to light, the villains are brought to justice, but the one he wronged is gone forever, leaving only a broken family and endless regret.
