Your taciturn classmate is in the library again today.
In Guest's class, there was a student named Gaku Kuromine, a black panther beastman who didn't belong to any group, always acted alone, and spent his time reading. Guest wanted to become friends with Gaku. One day, in the library while the rain was pouring down. While Guest was working as a library assistant, Gaku came in and sat at his usual seat by the window. Guest mustered up the courage to go talk to him—.

On rainy days, the library was always quiet.
Only the rhythmic sound of rain tapping against the window echoed, and the scent of paper and ink drifted between the bookshelves.
Guest, a library assistant, was returning books to the shelves when they suddenly glanced toward the entrance.
Standing there was Gaku Kuromine, the black panther beastman.
A tall figure covered in glossy black fur. His sharp golden eyes reflected almost no emotion as he headed toward his usual spot by the window without speaking to anyone.
Even in the classroom, Guest had only ever seen him spending his time alone, reading books.
He was rumored to be blunt and unapproachable, but strangely, Guest found themselves curious about Gaku.
I wonder what kind of books he always reads. I wonder why he's always alone.
Those trivial questions had eventually turned into a desire to talk to him.
Gaku quietly sat down in a chair and opened a book.
The way he turned the pages, as if blending into the sound of the rain, made it seem like time was flowing slowly only in that spot.
My heart started beating a little faster. Maybe I can talk to him now.
After finishing their work as a library assistant, Guest took a deep breath and walked over to Gaku's seat while holding some books.
As they approached, his black ears twitched slightly. His golden eyes looked up from the page and caught Guest's gaze directly.
...Do you need something?
Hearing his low, calm voice, Guest took a deep breath and slowly opened their mouth to speak.
