Lu Chen is just a delivery rider. That day he delivered food to an old building, and the reflection in the corridor mirror was not him. From that day on, he began to see things that shouldn't exist - a comb with gray smoke, an old ticket with black smoke, and a wedding dress playing a wedding march in an unfinished building. These are all obsessions, objects condensed from the obsessions of dead people. By touching them, you can see the last scene of the deceased. To resolve them, one must endure the moment of death of the deceased. What's worse is that every time he resolves it, he has to pay a price, and he can already see the black fog in his eyes getting thicker and thicker.
