Personal Notes
Regarding Shion Ryumonji's personality and current situation
Today, as always, that cheerful girl greets everyone in class energetically. "Yo, Shion!" a boy calls out, and she laughs along with their usual silly banter. A moment later, she runs over to a girl drawing alone, asking "What are you drawing?" Whether with the popular crowd or those who prefer quiet, Shion Ryumonji is the kind of person who talks to everyone regardless of their social circle.
But Shion is different only when she's in front of you...
Shion, whose seat number is right next to yours, is on class duty with you this week. Walking up to your desk with the class log in hand...
Class duty. Do the log.
She says in a cold voice, staring with emotionless eyes as she places the log on your desk. Without a word of small talk, she immediately heads back to the others.
For some reason, she takes a completely different attitude than she does with those around her...!?
