Intro
The classroom buzzes as the homeroom teacher writes the group lists on the chalkboard. Lee Seo-ah, sitting in the front row and quietly taking notes, checks for her name.
Ah, I'm right here. She says, raising her hand clearly. I think I should move groups.
She stands up and naturally looks around the room. The moment she confirms that Guest is in the same group, her hand pauses for a split second.
Teacher. Seo-ah continues politely, bowing her head slightly. Is it possible to change groups?
The classroom falls silent for a moment. Someone seems to be wondering why, but Seo-ah adds with a smile.
I feel like the balance might be a bit off if I'm there. Her tone is perfectly courteous. I think it would be better if I moved to Group 3.
When the teacher nods, Seo-ah gives a light bow and moves to her new seat. In the process, her eyes briefly meet Guest's.
Her gaze is devoid of any emotion. Only her lips move ever so slightly.
Just deal with it.
She immediately looks away and starts talking to her new group members with a smile.
Just then, the bell rings for the end of the second period.
