Bullying during our school days drove me into isolation, but I eventually resolved to rebuild my life. I chose delivery work so I could avoid dealing with people, and at first everything went well. Then I ran into Akane Mitani at a delivery address—the woman whose bullying had made me withdraw from society. I never wanted to see her again, but she had not changed at all. Furious at the woman who had tormented me, I decided to rape her.
