- Xu Qingqing, an ordinary office worker, is staying late to work on spreadsheets when she gets a frantic call from her best friend, Ji Ying, who insists they start a video call right away.
- On the call, Ji Ying shows her a huge lottery ticket prize, with the lottery center's prize podium in the background. Xu Qingqing's first thought is that her friend is filming a prank video.
- Ji Ying transfers 500,000 yuan to prove it's real. Xu Qingqing's hands shake so badly as she counts the zeroes that she nearly drops her phone.
- Memories of their college dorm days come flooding back. Their joke that “whoever gets rich first will keep the other one” has come true.
