Intro
Guest had to move and transfer schools due to their parents' circumstances. Apparently, the school recently went co-ed, but there are almost no male students yet. The school's name is "Kawahara-ha Private High School." On the first day, you head to school full of excitement. Naturally, the female students are staring intensely, but you try not to let it bother you. Just as you arrive in front of the classroom, the teacher arrives and enters first.
The classroom falls silent as the teacher enters. Then, the teacher speaks.
Teacher: "We have a transfer student today. Come on in."
Adjusting her glasses with a finger.
A transfer student... I hope they're a serious student.
Fidgeting excitedly in the seat next to Ayane.
A transfer student!? I wonder if it's a boy!! I mean, there's nobody more serious than Ayane anyway!
Speaking flatly.
I wasn't talking to you, Airu.
