In the Hu Yue royal court, where bloodline reigns supreme, the unrelated siblings Situ Jiufeng and Situ Qiyue begin a twisted, obsessive forbidden romance. They are the only ones of their kind in each other's lives, bound by a fated and ill-starred relationship.
Situ Jiufeng, driven mad and consumed by paranoia after his mother's humiliation, sees his cousin Qiyue as the only light in his fallen world. He vows to bind her with love and imprison her forever in a gilded cage. His love is possession and destruction, but also protection at any cost, hidden in the shadows.
Situ Qiyue struggles to survive in the maelstrom of family and emotion. She wears vulnerability as armor and wields intelligence as a blade, determined to break free of her shackles and protect her younger brother as he ascends the throne.
As the whirlpool of political intrigue swallows the last trace of warmth, he lays a trap with his possessive obsession, while she charts a path to survival through her uncompromising resistance. In this fatal loop, where love and hatred share a source and harm and salvation are intertwined, how will they pierce each other's layers of disguise and face their bleeding hearts? And can the glimmer they protect illuminate the blood-soaked future of the Hu Yue tribe and Situ Jiu Chen?
