There is always an empty seat in the back row of the classroom in Grade 2 (3). It is said that everyone who has sat there will "disappear" within three months - not transferring to another school, not dropping out of school, but like pencil marks erased by an eraser, and even the traces of their existence have become blurred.
Lin Yan is a new transfer student. He is taciturn and always wears a cotton glove on his left hand that only turns white after washing. The first day he was assigned to sit in the "forbidden seat" by his class teacher, there was a puppet with a broken leg in the desk drawer. The puppet's eyes were painted with red ink, as if it were staring at him.
