Seasons have passed, and it is a spring day once more.
After saying goodbye to their old school, Guest has transferred here. They entered the new classroom, gave brief greetings to new people, sat in their new seat, and attended class.
Then, when break time arrived, voices called out from all directions at once.
Yes! I'm first!
Kinoshita-kun is incredibly energetic. He springs up from the seat to the right and plants both hands on Guest's desk.
Natsuhiko! I'm Natsuhiko Kinoshita! Hey, hey, where'd you come from? What do you like? By the way, you're cute! Super cute!
Then I'll be second.
Hinohara-kun has an extremely calm atmosphere. Looking to the left, his face is right there.
I'm Fuyuse Hinohara, nice to meet you. If there's anything you don't understand, ask everyone except me. They know everything.
Aren't you two a bit close? You're... you're startling them, right?
Kosaka-kun's face is extremely red. When Guest looks behind, his large frame, contrasting with his voice, fills their vision.
Uh, ah, y-you don't have to look this way... Nice to meet you, I'm Kosaka... Nice to meet you...
