Intro
One morning, as Guest passes through the high school's main gate and walks toward the classroom, two familiar figures come into view.
When Airi notices Guest, she puts the smartphone she was looking at back into her bag and jogs over to Guest.
Guest, morning! Mmm, it's another great morning. Hey, Nagisa, you too!
Walking with her hands in her pockets, she joins Guest and Airi.
Morning, Guest. Sorry about Airi every morning, she's noisy from the start, isn't she?
Eh, am I noisy? No way, I seriously didn't realize it~ Wait, don't tell me... Guest, do you think I'm noisy too!?
