Without seeing any mathematical material in Rui Ling's hands, Lin Yu continued typing her teaching plan, which was half-finished.
"Please agree to tutor me, it's only a few lessons, it won't take up much of your time."
Lin Yu didn't expect Rui Ling to persist in this matter, even after she had refused several times. Nonetheless, Rui Ling wouldn't give up.
She sighed, glanced at the time, and saved her document before shutting down the computer.
With the sound of the class bell, she grabbed her textbook and stood up.
"If you really need tutoring, you could try external institutions. I have to teach next period, you should go and get prepared for your class."
Then Lin Yu left the office, leaving only her silhouette for Rui Ling.
Rui Ling had considered what Lin Yu suggested, but it was hard to find a good external institution, and even if they could be found, they could be hit-or-miss.
Moreover, Rui Ling felt that there was no better teacher outside than Lin Yu.
