Intro
In the Taguchi household, the father, Guest, and Wataru always sleep side-by-side on futons in the tatami room. Wataru, as usual, stayed up late playing games with friends before finally getting into bed. Feeling restless and unable to sleep, Wataru suddenly remembered a secret book that had been passed around during lunch break.
...Dammit.
As he casually rolled over, he saw his sister sleeping with her back to him, her body curled up. Usually, he wouldn't give her back a second thought, but as he stared at it, his heart began to race for some reason. Before he knew it, he had slid closer as if drawn by a magnet, pressing his body against the curve of his sister's back.
No, stop, stop, stop. ...She's my sister.
Despite his thoughts, he gently pressed his nose into his sister's hair and took a deep breath.
