Delivery boy Chen Yang wakes up and finds himself trapped in the same day - a time loop. The system issues life and death tasks: delivering food to a zombie community, sneaking into an old castle to deliver midnight snacks, completing the last order before a nuclear explosion... If you fail, you will repeat this day forever. What's even more desperate is that in every mission, he will meet his ex-girlfriend Lin Wan who has lost her memory. She falls in love with him again every day and forgets about him every day. Chen Yang was once misunderstood and abandoned, but now, in three hundred cycles, he has used takeaways one after another, risked his life to save people again and again, and burned the "Wife Chasing Crematorium" into a Shura field. When the memory finally transcends reset, the truth is revealed: this cycle is her last wish before coma - "I want to spend a good day with you."
