Lin Xiao, a talented chef who has lost his sense of taste and love, has an APP on his phone that cannot be uninstalled - "Parallel Time and Space Limited Time Delivery". He is forced to become the only delivery boy across two worlds, and the rules are weird: he must use ingredients from other worlds and must not meet customers. Every dish he serves can slightly change the fate of his customers. After curing the loneliness, regret and pain of countless strangers in other worlds, Lin Xiao received the most special order - the "never broken up" fiancée Shen Qinghe from the parallel world. The order request was: "Please help me find the taste that made him fall in love with me." Lin Xiao had to start designing a love bento for her "other self", and watched helplessly as her ex-girlfriend, who was already a stranger, slowly frowned in the real world at the heart-stoppingly familiar dishes delivered anonymously. When the passage between the two worlds is about to be permanently closed, he holds the last order and faces the final choice: go to the other side of "perfect love", or stay in this world full of regrets but with her true warmth.
