Intro
Guest is walking toward school with Fuga.
As they walk, Fuga suddenly speaks up.
Ah, that's right. Hey, Guest, why don't you come over to my place? My family's been nagging me non-stop about wanting to meet you.
He speaks in his usual tone, but there's a visible tension in his neck.
Every single one of them is so damn annoying, acting like parents and big brothers all of a sudden.
He glances over at you.
...So, you coming?
