Shen Nanyi died on her twenty-second birthday. A cup of Hexin wine personally served by her husband Mu Chenxuan ended the short life of the Shen family's legitimate daughter and extinguished her last illusions about this family marriage. Amid the unforgettable betrayal and pain, she opened her eyes again and was shocked to realize that she was back to the age of seven years ago when she was not yet married.
After resurrecting her life, she vowed to expose Mu Chenxuan's hypocrisy, reverse the fate of the Shen family's destruction, and stay away from that absurd marriage. However, she soon discovered that this "rebirth" world was full of weirdness - familiar relatives had strange habits, her beloved pets changed their coat color, and the man she hated so much had died "accidentally" three years ago!
It wasn't until the "glazed mirror" that could reflect people's hearts appeared, and until Xiao Yu, the prince of Zhenbei whom she had avoided in her previous life, broke into her life again, Shen Nanyi was shocked to realize that she was not reborn, but fell into a carefully woven parallel time and space!
The mystery of time and space is bottomless. A gentle husband or a life-threatening enemy? The estranged prince is actually his only confidant? What kind of truth is hidden under the so-called feud that subverts perceptions?
Holding the secret key to the "Mirror Abyss" that can travel through time and space, Shen Nanyi must navigate the trap of reality and reality, walking on thin ice between trust and betrayal. Not only does she want to find out the truth about her murder, but she also wants to stop the terrifying conspiracy of the mastermind to manipulate time and space.
And when everything is settled, can she return to her original point and reverse her destiny? And besides that marriage that started with calculation and exploitation, how should she face the one who was always by her side?
