There came through the paper an appreciative moan, quite feminine. She heard sheets rustle, she heard the creak of the floor boards (senpai always said he should get those replaced, she remembered). Sakura heard then, in the silence, in the blackness of the night and the soul, the quiet sound of a kiss.
Somewhere far along this road, he lost his soul ‘Please don’t do it, please, please, please…’ He had confessed to her, she had heard him say that he loved her. She still had a small amount of respect left for her upper-classmate. She wanted to barge in, she wanted to yell and scream and accuse, but she still had faith. ‘Don’t listen senpai, don’t!’ Sakura pleaded with him in her mind. “Shh,” Rin’s soft and seductive voice whispered through the air as though it came from wind carrying poison. “Tohsaka-“her senpai’s voice came through, as innocent and naïve as always. It perfect night, a picturesque darkness. All the lights were turned off the moon was hidden by the clouds. “It’ll be alright Shirou, Sakura will never find out,” her sister’s voice came through the thin paper walls. Her body burned with shame and the anguish of any human who has realized that they’ve been played for a fool. It holds all the stories that ever will be and ever were. In time, Shirou forgot all about the book, and what it might hold. Kiritsugu nodded, and put it back, and it was never mentioned again. Shirou hesitated, and eventually shook his head, "No, forget it dad. He stretched out his arm, offering it to Shirou.
Kiritsugu sighed, and went and fetched the book. "But that doesn't make sense! That book is huge, how could it only have one story?" Shirou was naive. "Dad, was that the only story in that book?" So one day, Shirou asked Kiritsugu a question. It was a big tome, far too big for Shirou to carry by his little self, and yet that was the only story in there? But Shirou was scared to open that book and look for himself. Because he didn't want to hear any more of Kiritsugu's bed time stories. "He died," Kiritsugu said flatly, "like everybody eventually will.
"But dad, what happened to the man?" young Shirou questioned. After some time passed, there wasn't anymore. So, Kiritsugu sat Shirou on his lap and read him a book. One night, when Shirou was thiiiiiiiiis widdle, Kiritsugu came in to find he was having a bad dweam.
