Reborn to Open a Supermarket in the Apocalypse

[Space + System + Apocalypse] In my past life, I was abandoned by my companions while escaping, betrayed by my boyfriend and best friend, and left with a dismembered body. Now that I've been reborn, I won't let any of these scumbags or bitches go unpunished. Just wait for me to slowly torment you all! In my past life, you stole what my grandfather left me; don't even think about touching it in this life! One day, I'll sacrifice all those who bullied and humiliated me in my past life to the heavens!
