Happy Maji

SSR-ranked killer Mu Hui died in an explosion, only waking up to find herself transmigrated into the body of a vicious female supporting character in a book.
The original Host was as stupid as a pig. As the lover of the villain, she helped the male protagonist steal the important documents from the villain and backstabbed the villain for the male protagonist.
The ending was, of course, being attacked by both the male protagonist and the villain, and, dying miserably.
And the point where Mu Hui transmigrated was the moment when she stabbed the villain and ran to the male protagonist's side—
What could she do to change her fate?
Mu Hui made a prompt decision and placed the knife that had stabbed the villain onto the male protagonist's neck. "The scene just now was deliberately acted out by my man and me. Return the document to my man immediately!"
The male protagonist: ""???""
The antagonist: ""???""
Later on, Mu Hui constantly helped the villain Fu Siye fight monsters and level up, just so that she could live longer and return to her original world.
However, one day, after a bath, the villain came up to her. "You've been my lover for so long. When are you going to consummate your marriage?"
Mu Hui: “???”
This was not how it was written in the book!

Fu Sichen was about to speak when Mu Hui splashed a glass of cold water on Fu Sichen's face.

"If you don't know how to speak properly, I'll wash your mouth for you. I'm warning you, Fu Siye has a fever and needs to rest. If you continue to chatter, you won't be splashed with just cold water the next time!"

Fu Sichen was drenched from head to toe. Losing his status in front of so many people made him even angrier.

Fu Sichen gritted his teeth and glared at Mu Hui angrily.

"How dare you splash water on me?"

He wanted to teach the b*tch a lesson, but the image of Mu Hui aiming her gun at him was still vivid in his mind.

Fu Sichen was terrified, but he refused to admit defeat.

"You haven't even entered the house yet, and you're already acting like the mistress? What arrogance! Mu Hui, your relationship with Fu Siye hasn't even been settled yet. Grandfather will never let a woman like you enter the house!"
