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!
[Even if it is meant to be, it can be changed step by step.]

When Mu Hui woke up, she found herself in a warm embrace.

She was stunned. There was a handsome face right in front of her.

Fu Siye was still sleeping. His curved and beautiful thin lips were pursed tightly, and a small row of fan-shaped shadows could be seen under his eyes.

She could feel his light breath on her face. A pleasant scent of cold wood lingered on his body. His eyelashes were long.

Mu Hui's heart skipped a beat, and her gaze stopped involuntarily on Fu Siye's thin lips.

A strange thought suddenly crossed her mind. Such lips should be very comfortable to kiss.

She was engrossed in her thoughts when suddenly she bumped into a pair of deep and dark eyes. They were like bottomless whirlpools. They were so mesmerizing that she was unable to extricate herself from them.
