@Freestyle Maybe it's about not passing the exam, or because he wasn't able to visit his family before becoming a tutor, or just an excuse so that he won't receive a flaming bird to the face
Lol Writes mail to a girl that probably has a crush on him, tell her not to cast magic at him next time they meet, also tells her that he’s hanging out with two cute girls.
"They are very cute girls, you see."
i can foresee an angry girl coming abruptly into the mansion to greet the guy with a "flaming bird" to the face in the near future
@welcome2atlantis maybe to spy on the one who has entered the library, or he was just startled and it is his natural reaction. @luminary I think it was referenced in chapter 4 as one of the advanced magic techniques associated with archducal households(probably the one Lydia hails from).
