Hidden in the city is Yi Mi, a house that only insomniacs can see. When the city falls asleep, but some people can't close their eyes, it will appear around the corner in the fog. The people living inside are all the same people who have been abandoned by sleep. Some are holding unhealed wounds in their arms, and some are hearing unforgettable voices in their ears. They didn't inquire about each other, they just kept their sobriety and recognized each other in silence.
Concept: In the dark night, a group of sleepless souls recognize each other and illuminate each other while awake.
