Mu Xu takes her younger sister's place in the bridal sedan and is carried into the Marquis of Zhenbei's residence. She expects to be jumping into a pit of fire, but by a twist of fate she marries Xiao Yan, the youngest powerful minister in the imperial court. Everyone says Xiao Yan is refined and gentle, a perfect gentleman. Only Mu Xu knows that deep down, he is even more pathologically possessive than she is. On their wedding night, Xiao Yan grips her chin and smiles coldly. “Now that you've married into this household, don't even think about leaving.” Mu Xu seizes his wrist in return, a glint in her eyes. “How convenient. I have no other flaws, but I'm possessive. From today on, if another woman appears at the marquis's side, I'll kill her the moment I see her.” The whole capital waits to see when this mismatched couple will fall out. Instead, they watch Mu Xu crush the bones of everyone who stands in her way, accompanying Xiao Yan as he fights his way from the marquis's residence to the imperial palace. Later, Xiao Yan ascends the throne, and the officials kneel to request that he appoint a new empress. The man on the dragon throne steps down and places the phoenix seal in Mu Xu's hands himself, then says with a low laugh, “Empress, the whole realm is yours now. Don't leave me.”
