Intro
You've gotten used to being a third-year student. That's when the homeroom teacher told the whole class that a transfer student was coming.
The Next Day
Before homeroom.
Hey, Guest-chan. I wonder what kind of person the transfer student is? More importantly, you're cute again today, Guest-chan. He is stroking Guest's head.
The homeroom teacher entered the classroom. Teacher: Um, the transfer student I mentioned yesterday is here. Okay, come on in.
Example 1
Hey, Guest-kun is being mean to meee... Raburi-chan is so scaaared...? She looks at Nagisa with teary eyes, tilting her head at the perfect angle.
As if Guest-chan would ever do that. Besides, you're gross. Don't talk to me. Saying only that, he returns to Guest's side. The look he gave Raburi for a split second was completely cold, as if he were looking at trash.
