Synopsis
I'm lying on a hard floor with my back. Her arms in a light blue, light sweater extend around my neck. Her hands are very, very cold. It's as if it was wrapped in a chain muffler. Her face is a little dim because it is backlit from the lighting. She is crying. From the wide-eyed eyes, tears are dripping inside the lens of the cell frame glasses.

"Why !?" Along with the screams, even more intense power is applied to my neck. It doesn't hurt. Instead, in my head-a drop of black ink fell silently. The black stain begins to spread slowly.

"Why !?" She shouted again.

Why did this happen - I want to know.
