The protagonist is an ordinary delivery boy who has lost his memory. He is pulled into a "ghost delivery platform" composed of obsessions from the underworld. He must survive by delivering "obsession orders". Each obsessive body has a "House Meal Collection Rules" related to its death experience during life. Violation of the rules will trigger fatal supernatural events. The protagonist's power is that when he touches the text or objects of the rules, he can see the memory fragments of the deceased, thereby deducing the "correct solution" and "hidden loopholes" of the rules. He must not only abide by the rules, but also find out the cause of death of the obsessive body in the gaps in the rules. Only by completing the transcendence can the food delivery level be improved.
