Hapbeopjeong Agyeogui Sajeong

I have to survive, no matter what!
I've died and been reincarnated as the villain of a romance novel! In order to avoid the hideous fate that awaits me, I've righted her wrongs and even gotten engaged. I should be home free, but strange things have started happening ever since the heroine appeared. Why won't her fiancé leave me alone?
