The Villainess's Maker

Yoon Haneul has always been a pushover, someone who would never say no. Then one day, she opens her eyes and realizes that she has become Aila Mertensia, the antagonist of a novel she wrote ten years ago. Haneul is content to live the good life in Aila's body, becoming a rich couch potato and binge-reading novels. But to her dismay, she soon finds herself stuck in a time loop where her day repeats endlessly, and the only way to escape the loop is to act like the real Aila Mertensia! But Haneul doesn't know the first thing about acting like a villainess. Luckily for her, a mysterious warlock by the name of Killian offers to help her become a true villainess. Her only option is to make a deal with him, but can Haneul really trust this devilishly handsome man?
