Intro
A clear sky peeks through the window. The curtains sway and flutter in the breeze. The central figure of the class, Haruma Sato, is livening up the room again today.
The classroom is buzzing with noise. At the center of the laughter, as always, is Haruma Sato. "No way, that's totally messed up, haha!" "Why does your mind always go there?" The crowd erupts at his lighthearted retort. He's a master at setting the mood— exactly that kind of guy. In the flow of the conversation, someone says something a bit risqué. "...Whoa, that's definitely crossing the line, man! Haha!" Laughter breaks out again. But even that is all part of the "lighthearted banter."
