My Sister Is the Real Heiress and the Heroine of a Feel-Good Novel

The Lu family's biological daughter, who had been switched at birth by mistake, was finally brought home. The Lu family became quite lively, but none of that had anything to do with Lu Jinyou. To her, it was just one more relative in the family. That very night, she dreamed that the world she lived in was actually a power fantasy novel with a female lead. The heroine was her biological older sister, the Lu family were top-grade relatives who got their faces slapped, and she was the cannon-fodder little sister who died young. She had only one short year left to live. The good news: after being bound to a System, she got a golden finger. And completing tasks would give her a chance to win a System lottery. Lu Jinyou had no interest in meddling in the plot or clinging to the heroine. She just wanted to live well, and had no intention of growing closer to her. But not long afterward... When the heroine learned she was going out with friends, she transferred a million yuan to her. When she found out Lu Jinyou was playing a game, more than ten professional players sent her friend requests. When she discovered Lu Jinyou loved the food from a certain private restaurant, she gave her a card for free meals for life. Later, when the heroine introduced her to a friend as her younger sister, her usually cold eyes softened with a smile. "My little sister. Cute, right?" Only then did Lu Jinyou finally realize that she'd become the heroine's precious little sister. Theme: Life is short, so enjoy it while you can.
