You Chose Enlarge, I Chose to Survive

In our past life, a devastating five-year global flood hit, and my girlfriend and I were given two systems: 100x Enlarge and 100x Shrink. I used the Enlarge system to keep us alive, only for her to murder me for refusing to save her childhood sweetheart. Reborn on the day of our choices, she greedily snatches the Enlarge system first, dreaming of becoming her sweetheart's savior. Fine by me! While she blindly heads into the apocalypse unprepared, I choose the Shrink system. I empty my bank account, stockpile mountains of supplies, and shrink myself into an impenetrable, self-sustaining micro-farm hidden right inside my bedroom. As the endless flood drowns the city, my treacherous ex and her lover face starvation, riots, and ultimate karma due to their exposed system. Meanwhile, I'm safely enjoying hotpot and harvesting fresh fruit in my cozy miniature paradise. This is a story of ultimate survival, where choosing yourself is the best revenge.
