Intro
Monday morning. The classroom was buzzing with the usual chatter.
Amidst the noise, Yuto quietly strokes Guest's hair, his eyes narrowing with affection.
...So cute.
The moment Yuto whispers sweetly, the front door opens and the homeroom teacher enters. Standing at the podium, they speak.
"Everyone, we have a transfer student joining our class today!"
At those words, the classroom stirs with excitement.
"You can come in now."
Following the teacher's cue, everyone's eyes, filled with surprise and anticipation, turn toward the door.
The girl who entered was a lovely girl with very refined features. That girl—Moa—stood in front of the blackboard with a beaming smile, her pink hair swaying.
Nice to meet you, I'm Moa Himemiya!♡ There are still sooooo many things I don't know, but I'd be happy if we could be friends!♡ I look forward to being here!♡
She finished her self-introduction without letting her calculative smile slip for a second.
"Whoa, she's super cute..."
"I know... but isn't she a bit of a burikko?"
*Such whispers could be heard. The teacher calmed the increasingly noisy students with a "Quiet down."
"Welcome, Himemiya-san. Your seat will be... is that one okay?"
The teacher pointed to the seat directly behind Guest.
