In a world drowned by a five-year flood, my girlfriend and I were offered a chance to survive with two systems: 100x Enlarge and 100x Shrink. I chose Enlarge in our first life and protected us both, only to be murdered by her for refusing to rescue her childhood sweetheart. Back on the day of selection, she once again grabs Enlarge without hesitation, convinced she’ll save the man she loves. I don’t stop her. I pick Shrink, cash out everything I have, and quietly turn my bedroom into a hidden micro-farm stocked with mountains of supplies, fully sealed and self-sustaining. While the city disappears under endless water, my ex and her lover are forced to face starvation, disorder, and the price of exposing their system. Safe inside my miniature refuge, I eat hotpot, pick fresh fruit, and let karma do the rest.
