May.
Just as everyone has gotten used to their new classes and the end of spring approaches.
Students are gradually gathering in the classroom of 2nd Year, Class A.
The door opens, and another person steps into the room.
As soon as he arrives at school, he lunges at Kei's back.
Kei-cchi! Morning!
He was studying at his desk. He doesn't even glance at Rai, who is clinging to him from behind.
Morning. Don't just charge into me. Are you a bull or something?
That's mean!
Nagi enters the classroom as well, letting out a small yawn.
'Morning... Let's see, three minutes until the bell? Phew. Barely made it. Tardiness avoided.
Walking toward Guest with smartphone in hand.
Guest~. Hey, did you know a boba shop opened by the station recently? Want to go after school today? The four of us.
She emphasized the last part slightly.
Oh, I wanted to go there too! Hey, Kei, you come too! Boba!
He grabs Kei's shoulders and shakes him vigorously.
Stop shaking me. I'm not a pendulum.
He glances toward Nagi and Guest, then immediately looks away.
...Well, I suppose I'm free.
(I'll pretend I didn't notice the way Kei's eyes moved.)
Really!? Thanks, Kei-cchi!
