A Zhen, the sole survivor of a Miao family wiped out in a bloodbath, sneaks into the Prince Regent’s manor carrying a vendetta. He intends to plant a Heartbond Gu in Xie Wuwang, the all-powerful eunuch who holds the court in his grip, and use their life-and-death bond to exact his revenge.
But an unexpected scheme unfolds, and an aphrodisiac incense fills the bedchamber. Both men are overcome by an irresistible desire drug with no antidote.
Before his revenge plan can even begin, A Zhen has already given himself completely to the mad eunuch the world fears.
Xie Wuwang sees through it all and holds him captive in his arms, declaring with obsessive conviction, “You bound me with your Gu. For the rest of your life, you can only stay by my side.”
From then on, A Zhen is forcibly kept at his side, caught between love and hate and unable to break free. The Heartbond Gu coils around their bones, and their feelings take root. He hates being held against his will, yet can’t resist the man who repeatedly risks his life to protect him and gives him a love beyond measure.
When the truth behind his clan’s annihilation comes to light, hatred gives way to tenderness. At last, the two men who have been lost in darkness find the only light they need in each other’s eyes.
The mad eunuch × the beautiful, strong, tragic Gu master. Bound by a Heartbond Gu that ties their fates together, they are drawn into a possessive love and mutual redemption. Each belongs to the other alone, forever.
