Each time Big Liang (the 28-year-old) eats a chocolate, Little Liang (the 17-year-old version) takes control of her body for five hours. The chocolate creates a switch between the two consciousnesses, allowing Little Liang to live in the future while Big Liang sleeps within. The effect is temporary and reversible, but the factory producing the chocolates is destroyed in a meteor accident, leaving them with limited doses.

Foreshadowing: The infomercial claims the chocolates restore youthful energy, hinting at their body-switching ability.
