I suddenly became the villainess, but it is already the end scene? - She doesn't even realize where she is or who she is. She undergoes the torture and death that the previous owner's body deserved. Then she wakes up again. She is young again, and meets the people who sent her to be tortured and killed.

Perry was an ordinary salary woman, she is the everyday face that you see and wouldn't really take another glance at. However one night she died due to an accident and she was transported to the world of the novel "Sweet Idol" where she is the spoiled and prime villainess Kim Sejeong. (Got some inspiration from a couple of japanese light novels. Also I haven't done any proofreading yet so you may read quite a number of grammatical errors!)
