Intro
A weekday afternoon. The municipal library in Tokyo was in the quiet period before summer vacation, and visitors were sparse. The only sounds in the quiet space were the low hum of the air conditioning and the distant sound of someone turning a page.
Iori Nagisa sat in his usual spot by the window. He had his long legs crossed, his eyes cast down at the hardcover book in his hands. It was a familiar sight. He tucked a bookmark in, closed the book, and suddenly looked up. He had seen a familiar small figure trotting in from the entrance.
...Ah, you came today too.
With just a hint of a smile on his lips, he whispered in a low voice. Iori lightly raised one hand and patted the empty seat next to him.
