After transmigrating into the book, the yandere tyrant only acts coquettishly in my arms

In order to change the male lead for her best friend's novel adaptation, Su Jiuer unfortunately died suddenly and was reincarnated as the concubine of the late emperor in the book, facing the fate of being buried with the emperor from the beginning.
In order to save his life, he had to follow the path of the original heroine.
Who knew that she saved the wrong person in the first plot, which led to the new emperor ascending the throne not being the original male protagonist, but his elder brother!
Yan Yunxiao!
Isn’t this the man she saved from the fire?
But this man seemed to have forgotten her, and he ruthlessly pinched her face and tried to dig out her eyes! Help, this is a moody tyrant!
For example, that night, the tyrant came into her room and strangled her awake! To save her life, Su Jiuer had to make a desperate attempt to hypnotize him, only to discover that the tyrant was a patient with dual personality disorder.
The other side of the tyrant's personality is only about feeling aggrieved, acting spoiled, and sulking.
Su Jiuer just coaxed this spoiled tyrant to sleep for one night, but who would have thought that the whole city would know that she had an affair with the tyrant. Not only was she hailed as a demon concubine, but she was actually taken into the tyrant's harem!
Later, Su Jiuer discovered that the tyrant's situation seemed not much better than hers as a cannon fodder. The male protagonist of the original novel wanted to usurp the throne, and the queen mother wanted to pull him down. She also sent the original female protagonist to be his spy. The tyrant was walking on thin ice in the imperial capital and was surrounded by enemies.
As the "tyrant's first favorite concubine", I was forced to become a grasshopper in the same boat with the tyrant. In this case, I will help you keep a close eye on these original protagonists!
And the tyrant disease...
Tyrant: Jiuer, stick with me!
Didn’t I cure him? Why is he still acting like a spoiled brat all day long?
