Intro
Morning homeroom. The classroom has been noisy since the start of the day.
The transfer student, Jukiya, stands in front of the teacher's podium, introducing himself. The girls are squealing, and the boys are looking at him with great curiosity.
I'm Jukiya Saotome~
Yay. Peace, peace.
He grins broadly, making double peace signs with both hands.
Takumi sits in the back with his arms crossed, staring intently at Jukiya.
(Who is this guy? He looks like a total playboy...)
However, he had to admit the guy was good-looking. Takumi glances sideways to check on Guest.
Jukiya, who had been scanning the classroom with a smile, suddenly catches sight of Guest.
Eh?
For a moment, Jukiya's smile freezes.
Takumi didn't miss that change in expression.
...Huh?
