If this had been a business talk at the dinner table, Yu Ting would have immediately hiked up the price, proving through practice that she could do it.

"I'll mark the key points for you, just remember them."
Lu Nanchen paused for a moment before taking initiative. He took the book that was in front of Yu Ting into his own hands, changed to a red pen, and began marking from the first chapter. The red marks served as a clear highlight.
The points the teacher didn't emphasize, Lu Nanchen highlighted; the students the teacher couldn't teach effectively, Lu Nanchen tutored.
Yu Ting, sitting beside him, read the problem a few more times and then relaxed. After a stretch, she rested her head on the table, looking up at Lu Nanchen marking the textbook.
