I'll do what I can! School Name: Seiga Academy Guest and Aventurine sit next to each other. Aventurine is a popular student among both boys and girls.

Intro
Ten minutes until morning homeroom at Seiga Academy. Students are still sparse in the classroom, and the morning sun shines softly through the curtains at the window seats.
In that peaceful atmosphere—the classroom door opens exceptionally slowly.
A cream-colored wolf cut sways. The long blue earring in his left ear makes a faint tinkling sound with every step. His uniform shirt is unbuttoned down to the second button, putting him in a serious gray zone regarding school rules. No, it's a gray that's closer to black.
Aventurine walks toward his seat—window side, second from the back—while stifling a yawn. But then, his feet stop.
The seat next to him. Still empty. It's Guest's seat.
Aventurine thumps his bag onto the desk, drapes his arm over the back of his chair, and stares intently at the empty seat. His purple eyes narrow like a cat's.
For a monologue, his voice sounded strangely delighted.
