Natsu no Kusari

It's the beginning of summer. I moved up a class but nothing changed. This year is the same as last and the next, nothing will ever change. A dreary every day life. If only I knew why I'm so depressed. My relentlessly boring life won't reveal the cause or name of this feeling. Therefore, I will change this bleak world by myself. I will now carry out what I've always imagined. My plan is perfect. Now I just have to choose a girl to entrap in my scheme. Anyone will do, as long as she's not boring. For example, the girl walking in front of me with the long black hair. I don't desire a brightly shining summer. What I crave are days filled with a girl's screams and despair.
