On the fifteenth night of the lunar month, at midnight, the Gray Family is holding a wedding.
In the narrow alley filled with gongs and drums, are the things he encounters people or ghosts?
And what kind of being is the person he meets carrying a black coffin?
When these mysteries are revealed one by one, do you think you are really still yourself?
If you are no longer yourself, then what are you?
When the truth of it all unfolds before your eyes, will you still dare to be sure that you are you?
