When Ichika was raped by her teacher as a student, she became a member of society with fear of men and distrust of humans… with a heart of darkness in his heart. I want to have a normal life… Just when I was about to take a step forward, the neighbor's garbage problem started. The true identity of the crappy neighbor living in the overflowing trash pile is a former teacher who was in prison for the crime of Ichika 10 years ago! Not even afraid of the worst possible coincidence, the imprisoned Ichika continued to be raped while her slender body creaked.
