"Interrogee": "When he went to visit the library the second time, there's a collision between a man and that boy, and the boy fell down. The man entered the library, and he saw that four goons were chasing that man. As usual, the boy entered the library, and then he went inside. He saw that the man is hiding behind the shelf, and the goons were also there."
