When My Pet Became the Villain

The villain was reincarnated as an extra in a novel where she was destined to die early. What would you do if you were reborn as such? 18 years of living as a slave after being mistreated by her family. Just as in the original book, I succeeded in running away, just before my parents forcibly sold me to the villain. I also spent a short but happy time with Momo, a dog I met in a rural village. But three months later, the dog I pampered and took care of disappeared! I was then caught by my family and sold to the villain. However, just when I was expecting to be killed... “Why are you so surprised? It's me, your puppy Momo.”
