Bobby ignored the voice in his head and left the Hollow Building. After he left the building, a slightly angry laugh came from a hidden attic. "What an arrogant brat. How dare he ignore me..." From the moment Bobby entered the Hollow Building, he hadn't taken the voice's warning seriously. Bobby had done whatever he wanted to. All he had to do was follow the rules; everything else didn't matter. His thought process wasn't wrong because, at the end of the day, he wasn't breaking any rules. However, Bobby wasn't aware that the mysterious voice in his head belonged to a high authority member in the clan. Even internal students respected him.
