Ten years ago, after their sister Pu Yangxu was kidnapped and murdered, everything changed silently and was out of everyone's control.
Happiness disappeared with the death of Puyang Xu.
Puyang Xiu, who cannot extricate himself from nightmares and self-blame, Puyang Hai, who is entangled in forbidden love, and Puyang You, who always lives in restraint...
The pain has left deep traces in their lives. Hatred, obsession, fantasy, admiration, and intertwining have become sins that they can never turn back. Light and darkness have woven into their endless lives.
From the beginning, they were headed for doom.
