Deplorable. Pleading Mournfully

Pete was just having a completely decent conversation with the principal of Foreign Languages High School, Principal Zhang, and was being showered praises by the latter when his basking moment was shattered the second he saw Yun Jian.

Despite twisting his ankle, Pete could care less about the pain. His gaze on Yun Jian was fearful like he was scared of the girl coming for him.

At the same time, he told Principal Zhang, "P-principal Zhang, I'll have to take my leave. Let's talk about this another time."

"Huh, Mr. Pete…" Principal Zhang started saying but Pete was already turning and running to the classroom building. Surprised, he was also suspicious when he saw Pete making his way there.

Why was Mr. Pete running to the teaching building when he was going to leave? Should he not be going for the school gate like where he had come from?
