[True and fake daughter/anti-routine/no female competition/sober in the world/weak CP]
Because Chen Yu slapped his best friend, he slipped into the novel written by her best friend and became a vicious female supporting character with the same name.
In the book, Chen Yu is brainless and vicious. After being recognized as the eldest lady by the prime minister's office, she works hard every day. In the end, she fails to seduce the tyrant, and ends up being beaten into a stick by the tyrant.
However, on the first day of time travel, Chen Yu complained crazily after seeing the barrage because of the changed plot line.
Knowing that her actions in the book would forcibly change the plot of the novel in her best friend's real life, the character became various OOC and started a journey of anti-routine.
"Good girl, let's wait and see. I, Chen Yu, will never give up until your novel is ruined!"

The existence of the male protagonist in this book is just to prove that the female protagonist's orientation is normal, nothing more!
