"This is impossible, I only gave you one of the keys to the classroom," the homeroom teacher said, frowning at him.
Gu Zhihan instinctively retorted, "It wasn't me."
He had also put a lot of effort and time into the blackboard report; only if he had gone nuts would he destroy his own blackboard report.
"Of course, I believe that," the homeroom teacher was not doubting him, but merely shocked that there was a second key holder in their class.
"Then, have you given the key to anyone else?" the homeroom teacher adjusted his glasses on the bridge of his nose and continued to investigate.
"No," Gu Zhihan shook his head and then, as if something occurred to him, added with a frown, "But one key was lost."
"I can vouch for that too!" Luo Mengmeng again raised her tiny hand.
"We can vouch for it..."
The other students also raised their hands and spoke up.
"Yesterday, I saw Gu Zhihan looking for the key inside his desk hole."
"I saw it too."
