Chapter 321: A Meal, and Beijing University's Student Union

"Have you had lunch?" Seeing her walking over, Cheng Juan slightly lowered his phone and lowered his gaze. His voice was soft and gentle.

Lu Zhaoying, on the other end of the phone, got a shock.

Master Juan had always spoken to him with either an indifferent tone or a cold and emotionless one. Why was he suddenly speaking so gently and properly?

"Erm… Master Juan…"

"Nope. I just came from the library." Qin Ran was holding on to her black backpack, and her black laptop was stored inside her bag.

There was a lot of research work involved in the Nuclear Engineering course outside of class hours, so Qin Ran would always go to the library with Pan Mingyue once class ended every day.

Lu Zhaoying almost blurted that he couldn't get used to Master Juan suddenly changing his tone, but he immediately swallowed his words after he heard Qin Ran's voice in the background.
