I couldn't understand the oneshot without the context of the synopsis.
So, it's basically like this:
The MC transmigrated as the villain of her own novel. As her fate as a villainess is death, she decided not to act as a villainess cause she wants to live in luxury. Her breaking the villainess act resulted to the time loop. The ML(?) fed up with the time loop managed to find her, informing her that the only way to break the loop is to continue her act as a villainess and he'll help her to become one.
