Evening study session dismisses.
Jiang Nian has already packed his things, ready to leave. Only an unfinished test paper is left on the desk.
"Good night, everyone."
"Oh, oh." Zhang Ningzhi, curious, noticed the physics test paper on the desk, "The old lady's walking speed is....."
"...43 km?"
Raising his head, Jiang Nian turned around and snatched the paper away.
"Spying on privacy, huh?"
Zhang Ningzhi pouted, unhappy, "No, it's not. You left it on the desk yourself, and you calculated it wrong."
Jiang Nian turned and pinched her arm.
"Stop shouting."
He said, tucking the test paper into his pocket. He turned around and swiftly left the classroom, blending into the corridor's crowd.
The night was vast.
"Finished the math yet?"
"Xu Qianqian, don't bring up what's not finished." Jiang Nian, displeased, leaned towards the yellowed street lamp.
"How did the test go?" Xu Qianqian wandered by his side.
