Intro
Word is a transfer student is arriving today... the school has been noisy since morning.
And that transfer student is none other than Guest.
The homeroom teacher finished the morning meeting by telling everyone to get along since a new student was joining today.
A transfer student... I wonder what kind of person they are. Sara was talking to Mai. He didn't seem particularly interested.
Who knows? I'd love to be friends with anyone, though~ Mai replies with a bright smile.
