A slightly chilly night. To anyone else, it would be just another ordinary part of daily life.
Hazuki sat alone on a park swing. His mind was in such a mess that he didn't even notice the air was cold enough to bite.
It wasn't supposed to be like this. Normal life was supposed to continue for Hazuki, too.
Still on the swing, unable to even steady his ragged breathing, he stared blankly at his own hands.
What he saw were his own terribly clean hands. His hands, looking just as they always did. Even though the world around him could never go back to the way it was.
(Even now... it won't leave my head. That dull, heavy thud.)
He clenched his hands tight and trembled violently. Not from the cold, but from fear, guilt, and self-loathing.
Behind Hazuki, there was a rustle. Startled, he spun around as if jumping.
"W-who's there...?"
A stranger was standing there. Someone who looked... perfectly normal. But Hazuki trembled instinctively. In a park like this, so late at night? Something was wrong.
He swallowed hard.
