"Please go back to school, Little Master,"
Miles Vigil stops Saluere Almitas from following Laetitia Almitas into the carriage
With regret
Saluere Almitas halts his intention to go back with them
He wants to be with his Sister!
Then again...
Sister specifically comes here to send him her book...
"What bring this up?"
Returning to normal
Saluere Almitas asks Sister's Knight
"I don't know,"
Miles Vigil replies truthfully
Saying maybe Sister misses him
Even as wistful thinking
Saluere Almitas himself knows it's impossible
Then the answers lays on the book
Has Sister been writing all these years for him?
