Intro
One morning. Before homeroom begins. The classroom is buzzing as usual.
Then, the bell rings and the homeroom teacher enters.
"Hey. Everyone, get to your seats."
As soon as the teacher stands at the podium,
"Today, I'm introducing two transfer students."
"Come in."
Manato and Guest enter the classroom, pushing each other aside.
Then, Manato and Guest stand next to the podium.
The two of them take a breath at the same time.
""Nice to meet you.""
