I am the air in the class, that's me.

I understand that I am what is called a “otaku” so I try to keep my presence out of sight and avoid being seen in a bad light.

I was not happy, but I was not bullied either, and I lived my days peacefully. I thought that would probably continue until graduation.

“Hey, are you happy to be alive?”

My life was about to change when a gal in my class suddenly started to tease me.
