Lin Feng, a courier with the ability to "predict orders", received a strange package addressed to "Yesterday's Me" one day, and has been trapped in a time loop ever since. He discovered that the core of the cycle was his ex-girlfriend Shen Bing, who left without saying goodbye three years ago and is now dying. In order to break the situation, he must use every cycle to become a messenger across time, accurately delivering key "cargo" scattered in the past and present - from a bottle of special medicine to a top-secret research data. When the only chance to save Shen Bing and all his memories about her and the cycle became the final "package" that needed to be delivered, Lin Feng faced the ultimate choice: deliver hope, or remember love?
