After what had happened inside the garden, Victoria was now inside the household as she was already taking her private lessons with Elphius
"...and the thing is you have to find these kinds of books inside the grand library, Milady"
Elphius had been talking about the empire as well as some etiquette lessons towards the lady, however, Victoria seemed to be distracted by what had happened earlier.

It's because for this reason - she'll be able to review what Elphius was teaching her currently
"Milady, is everything alright?"
That's the time that Victoria went back straight to her consciousness and was about to look at Elphius when Elphius was already the one who faced her with his genuine smile
