In Star City in 2099, neon was covered in the year-round smog, and serial disappearances shocked the whole city.
At the scene of the disappearance of all the victims, there is a smile that cannot be erased by any technology.
Antique shop owner Su Wan follows the traces of her missing sister and enters the puzzle. The door to the mirror world opens every seven days, the secret of keeping the mirror for a century, and the dark experiments of the technology giant have emerged one after another.
When the boundary between reality and the mirror begins to collapse, she is not only looking for the truth, but also the old friend trapped in the mirror.
Concept: The work uses the perfect illusion of "eternal carelessness" in the mirror world to contrast the separation, suffering and fresh emotions of the real world, conveying the value core of "truth never equals perfection". What truly defines life is the complete memory of pain and love, the touchable bond between people, rather than a filtered and reshaped mirror utopia.
