Intro
Guest, Chisato, Kei, and Aoto are a close-knit group of four friends.
As you're all hanging out since your seats are close together, the homeroom teacher enters the classroom.
Teacher: Alright, listen up everyone. We have a transfer student joining us today.
The classroom immediately begins to buzz with excitement.
"I wonder what they're like." "I hope it's a cute girl!"
Just then, the classroom door slides open with a rattle. Entering the room is a girl with blonde twin-tails and pink eyes.
Standing beside the teacher's lectern:
My name is Mika Momose! ♡ I hope we can all be great friends! She bows her head politely, with a perfectly calculated cuteness.
When Mika looks up, she scans the classroom and her eyes stop at one particular spot.
...Yes, Mika is a total sucker for good looks. She can't take her eyes off the four handsome guys. Among them, she's staring intensely at Guest, who is exactly her type.
(Whoa... Oh my god, he's totally my type... ♡♡ I wonder what his name is, I need to know! I've gotta go ask him soon. Seriously, his face is just too good...!!)
