Synopsis
Mayu Misono. My classmate, intelligent, very beautiful, and very important person. She is now sitting next to me and laughing innocently. On TV in the living room with Mayu, an overview of the kidnapping case that took place in our peaceful city was shown.

Kidnapping is, in a sense, a more vicious crime than murder. The murder ends when he dies, but the kidnapping continues after he is released. You have to continue your life that is out of sync. It can't be fixed. While being enslaved to a normal person who couldn't understand.

──Ah, by the way. If you have time, ask a question next time. Ma-chan, why did you kidnap those children?

What?
