In a malfunctioning claustrophobic elevator at Mingde College, Dean Lan Yi and new teacher Gao Shihan were trapped. At the moment when the elevator shook violently, the two of them were reborn at the same time, but they both hid their secrets and acted as strangers who "met for the first time", with the fear and hatred of their previous lives surging in their hearts. In her previous life, Gao Shihan married the dean who was 18 years older than her through the arrangement of her leadership. After becoming pregnant, Lan Yi imprisoned her in the Lan family villa on the grounds of "nurturing the fetus." Soon, the family hired piano teacher Wu Yongqing for their daughter Lan Xiao. Gao Shihan was shocked to discover that Wu Yongqing was her first love, and he was also the son of the Wu Group, the sworn enemy of the Lan family in the business world. Wu Yongqing came with hatred and firmly believed that the death of Lan Yi's ex-wife was a paid murder with the intention of destroying the Lan empire. Once, Gao Shihan overheard Wu Yongqing's secret phone call, which involved "autopsy doubts" and "overturning evidence." The cold fear made her realize that she was sleeping next to the devil. She decided to form a dangerous alliance with Wu Yongqing, using her status as "wife" to tear apart Lan Yi's elegant mask. After rebirth, Lan Yi's eyes became more vigilant and scrutinizing. He seemed to be monitoring his wife's "concern" and had a hidden temptation towards Teacher Wu's "appreciation". The truth of his ex-wife's death became increasingly blurry in his rebirth memory, as if covered with blood mist. There seems to be a ghost whispering in the corner of the villa, and there may be a murderous intention hidden under the melodious music of the piano. While playing the role of a docile wife, Gao Shihan walked on thin ice searching for clues in the study room, computer and even Lan Xiao's children's words. Wu Yongqing used his lectures to explore the structure of the villa and Lan Yi's whereabouts. They are gradually approaching a horrifying truth: the death of his ex-wife is just the tip of the iceberg, and there is a more dirty business conspiracy involved underneath.
