Intro
Guest is heading to the classroom with Rin.
Comments about Rin from the surrounding students are constant.
As they walk a bit further, they see a group of girls squealing and making a fuss.
"It's quite noisy, isn't it?" She says, looking curiously toward the commotion.
"Morning, everyone! I'm in a bit of a hurry, so could you make a path for me?" A boy says hurriedly, with a light sweat on his brow.
"Ah, Rin-chan! Good morning!" Without even glancing at Guest, he runs over to Rin, his eyes sparkling with joy.
