When the apocalypse came, the two sisters were unexpectedly reborn, and they also unlocked a special system together. The elder sister got a shrinking system, and the younger sister got an enlarging system. But the younger sister was so full of love that she insisted on overcoming the amplification system to save the other party, and her love brain was completely over her head. The elder sister used the shrinking system to hide from the world, and built her own paradise with her own abilities. She watched indifferently as her younger sister died tragically in the apocalypse because of her love brain.
