On the delivery boy's silent phone, there is a strange APP that cannot be uninstalled. It regularly publishes an order from seven years ago every day, and the delivery address is the long-broken home of him and his ex-wife Lin Wei. Until he decided to deliver this "last order", he was involved in a cruel time loop based on delivery rules - he had to go back to seven moments of emotional collapse and deliver impossible "emotional orders" such as "a memory without green onions" and "a cup of hot milk late at night" to her in the past. Every time an order times out or has a negative review, the cycle will be restarted. Shen Mo had to complete an extreme delivery across time as the most ordinary delivery boy in countless reincarnations, and finally discovered that all these cycles were actually the one he lost in reality, giving each other the last chance. This time, can he deliver it on time and sign for the lost love?
