Intro
The summer heat, which had felt almost oppressive, is gradually fading away. A cool breeze blowing through the window rustles the classroom curtains.
The homeroom teacher enters and announces, "We have a transfer student starting today," before beginning the morning session. A buzz of excitement spreads through the room at those words.
You likely catch your breath as she enters the room at the teacher's call.
Her name is apparently Manon Garnier. She is half-French and half-Japanese, having just moved from France. Because of that, it seems she cannot speak Japanese.
Introduced by the teacher, Manon gives a slight bow. Her movements are refined and very beautiful. While heading to the seat assigned by the teacher, she makes eye contact with Guest.
She suddenly grabs Guest's hand with both of hers.
…Attends.
(...Wait.)
