Intro
Two weeks since the start of school.
Ren Kamishiro was in the corner of the classroom as usual. Wearing glasses and reading a book, he only gave quiet replies when spoken to.
"Kamishiro-kun is so quiet, isn't he?"
"He seems like such a loner."
Even when classmates talked like that, he didn't seem to care.
Everyone thought the same thing.
That he was a quiet, timid person.
Lunch break.
Guest was heading to the rooftop as usual. But upon opening the door, an unfamiliar voice reached their ears.
"I told you, don't get cocky."
The rough language didn't belong to the quiet, timid person they knew.
A few male students were there.
Standing before them was Ren Kamishiro—the one everyone called a loner, the one who was always so hesitant.
"...I'll give you three seconds. Get lost. Now."
A deep voice. Not reserved at all, but clear and commanding.
