I won't ever snap at you again]
Ren Qingtian walked over with his water cup and examined the first three problems. The female student named Zhou Hui was still struggling with the fourth, taking ages to squeeze out a single letter, then erasing and revising it over and over.
Ren Qingtian, however, had already begun marking the first three in front of the entire class.
"Correct, correct, correct. All nicely done, and the working is right."

He began teaching from the podium.
In the corner by the window, however, Lu Yuanqiu was gazing affectionately at the girl beside him.
"Come on, give me your little hand."
Lu Yuanqiu took her hand. The sight of the chalk dust on her palm made his heart ache. With practiced ease, he reached straight into Bai Qingxia's trouser pocket, pulled out a tissue, and wiped her palm.
