Xiao Ruyan felt a bit stifled in her chest.
It was as if her heart might leap out of her chest at any moment.
As a teacher, her observational skills were keener than most. She could tell whether students were genuinely reading or just using their books as a cover to read novels or comic books.
She could also discern if students were cheating during exams.
So,
The panic Xu Wendong showed when he looked at her proved that something was definitely up.
And the only possibility was that he had seen what she was doing earlier.
Her face turned crimson, and her cheeks felt like they were on fire, as though she'd lost all her dignity and wanted to find a hole to crawl into.
After the panic, what she felt more was gratitude, thankful that Xu Wendong pretended that nothing had happened; otherwise, she truly wouldn't know how to face him.
