She is an assassin ordered to kill the king, with only one mission - to kill the paranoid tyrant Xiao Jin.
He suffered inhumane torture in his childhood. On the outside he pretended to be a loving and wise king, but on the inside he was violent, bloodthirsty and lacking in love. He would die if others disagreed with him, but he made an exception and indulged her.
She deliberately got close to him, planned for him, became his only weak spot, and coaxed away all his madness and anger.
He was so possessive that no one could escape death even if he took a second look at her, and he could only pretend to be her.
She calculated every step of the way, but unknowingly she was sincere, and her desire to assassinate wavered repeatedly.
The half-brother of the prince, who was blamed for killing his mother, initially wanted to use her to exploit the tyrant's weakness and deliberately flirted with her, but in the end he fell deeply in love with her.
In the end, she was ordered to assassinate him, but she missed the key point, but broke his whole heart.
He did not kill her, but imprisoned her in the palace, tortured her every day, and forced her to serve with the women in the harem.
She escaped several times but was recaptured. The second male lead took her away and laid a trap to overthrow the dynasty.
The tyrant has betrayed all his relatives and lost everything. When the second male protagonist raised his sword to kill him, she flew to block the fatal sword blow.
She confessed her love on her deathbed, and the tyrant watched her die in his arms. He only had her sincerity in this life, so he drew his sword and killed himself, and went to hell with her.
