Agnyeo Maker

A woman who is typically agreeable discovers she has become the antagonist character from a novel she wrote a decade earlier. She is uninterested in taking on the role and prefers a relaxed, indulgent lifestyle. However, she becomes trapped in a repeating day, with the only escape being to embody the villainess. Unfamiliar with villainous behavior, she is assisted by a mysterious warlock named Killian, who offers to help her transform into a true antagonist. She must decide whether to trust him, despite her doubts.
