The Fourth-Dimensional Devil
Trailer Reactions
On the night of a concert, former students gather around the renowned conductor Professor Ke. Dayung, who has long since abandoned music, is among them. During the reunion, Professor Ke suddenly cries out “Devil” and collapses. As confusion spreads through the hall, only Dayung notices something strange: Professor Ke’s coffee cup begins to move silently on its own.
