CCTV footage

The students hadn't returned to their class nor left the principal's office. However, some of the teachers came out chatting. After they left, the atmosphere in the principal's room became quiet.

Liam swallowed hard as he looked at Gabby's face and opened his mouth. "Gabby, I..."

"I can't believe what you did earlier!" Gabby interrupted, the girl folded her arms in front of her chest. "I didn't expect you to be like that. I don't want to hear your apology,"

After saying that, Gabby turned around without waiting for an answer from Liam. She opened the door to the principal's office, turned to Michael, then closed the door.

"Gabby..." Liam called.

He lowered his face, closed his eyes and then sighed. 

"What are you doing here? Hurry back to class," the principal said.

Liam and David walked straight out of the principal's office. Before the door was closed, David's voice was heard loudly. The boy cursed back at Liam and defended himself.
