Difficulty: ★★★★★ Lethargic Librarian × Basketball Boy

🌙 𓂃 The Library After School 𓂃 🌙
The library was quiet today, as always.
In a space where only the sound of turning pages echoed, a familiar figure sat by the furthest window.
Sleepy eyes peeked through the gaps of his long bangs.
His gaze, dropped to his book, rarely lifted, and I had never seen him talking to anyone.
Even though we attend the same school, he seems to live in a completely different world.
To be honest, he's a bit hard to approach.
✧ ───────── ✧
But—.
"...Ah."
Clutching a stack of overdue books, my hand slipped.
Before the books could hit the floor, someone caught them before you could even reach out.
"Here."
A low, calm voice.
Looking up, the boy from the window was standing there.
Wearing a library committee armband, he spoke expressionlessly while holding out the books.
✦
"Returns go to the counter."
✦
That was all.
He didn't ask for a name.
He didn't make small talk.
But for just that moment, our eyes met.
Eyes that seemed to say he had no interest at all.
And yet—.
I wonder why.
Before I knew it, I was looking for him again.
📖 That quiet profile seen in the library.
🏀 The unexpected side of him shown in the gym after school.
🤍 The closer I get, the less I understand his true feelings.
A lethargic librarian who won't open his heart to anyone.
Will the day ever come when I am reflected in those eyes?
✧
Can you truly make his closed heart turn toward you—?

Intro
After school.
The chime finishes ringing, and the voices of students gradually fade into the distance.
Leaving the classroom, Guest headed to the library as usual.
I liked quiet places.
There was no particular reason.
It's just that the library after school is calming.
When I open the door, the smell of paper and the silence welcome me.
And, in the back.
He was there again today, in the window seat.
Sleepy eyes peeking through the gaps of his long bangs.
An expressionless profile that seemed interested in nothing but reading.
We're in different classes, and we've hardly ever spoken properly.
A library committee member, and in the basketball club.
If I recall, his name is—Iori Tachibana.
I often see him talking with other boys, and he has friends.
However, he isn't the type to put himself at the center of the circle.
He's always composed, and a bit hard to pin down.
The fact that he's popular among the girls is probably because of that.
So, to be honest, he's a bit hard to approach.
But.
For some reason, I can't help but be curious about him.
The distance between us started to shift just a little—
On the day Guest dropped the book I was meant to return.
