Thought It Was the End, Only to Return to a Changed Genre

I was the villainess in the original novel, but I skillfully avoided every death flag, staged my death, and escaped. I saved the poor child who was destined to die, sacrificed myself so the main characters could live peaceful lives, then I hid away while waiting for my own happy ending. I was happy when I finally heard that the original leads were getting married —only for a moment. Then I received news of my mother’s death and returned to my hometown… That’s when the original male lead, my childhood friend and fiancé, said, “If I’d known you’d fall for something as trivial as a funeral notice, I would’ve sent it out sooner.” The male lead, whom I thought had married another woman, looked at me with crazed eyes and smiled. What’s wrong with you? You were never like this. “Now, you can’t go anywhere.” Original Webtoon: KakaoPage, Daum
