After being called out by Vaan, Astoria was both embarrassed and angry at the same time. Unlike him, she had been quite discreet with her masturbation. And yet, she was still found out.
Evidently, he had quite the sharp sense.
However, it wasn't something he should say even if he found out; he had to avoid shaming witches. Otherwise, it would land him in hot water one day—if done to the wrong witch.
'There's no way that Teacher Raphna doesn't know this… He's teasing me because he knows he can get away with it,' Astoria thought.
Shortly after, she furrowed her brows and coolly said with a bit of admonishment, "Please respect my privacy and refrain from making personal remarks, Teacher Raphna."
"Oh?" Vaan's eyes flickered thoughtfully despite realizing his teasing had backfired. He replied shortly after, "I see… You're not very fond of this kind of talk. I'll keep that in mind in the future, Headmaster Astoria."
