After a tragic suicide driven by grief, a single soul awakens in the bodies of sixteen-year-old twin sisters, Xu Youyue and Xu Mingyue, in modern-day China. Blessed with breathtaking beauty and an hourglass figure that stops traffic, they quickly become the center of attention while working part-time at a milk tea shop. However, their new life comes with a deadly catch: the original bodies suffered severe organ damage from sleeping pills, leaving them with a theoretical lifespan of only twenty years.

Just as despair sets in, an 'Entertainment Pay-to-Win System' activates, offering a path to cure their terminal illness through earning money and mastering artistic skills. To survive, the protagonist must navigate the cutthroat entertainment industry, leveraging their dual identity to compose hit songs, direct films, and dominate the charts. Facing intense competition and the pressure of 'involution,' this unique duo must rise from street performers to global superstars before time runs out.
