She feels like she is always being watched. She consults her husband about it, but he doesn't take her seriously. The voyeurism escalates. And finally, her brother rapes her. Shiori desperately resists, but she is no match for him in strength. Even though she should hate it so much... Shiori feels uncomfortable while being violated. Shiori remembers something. That's right, she was raped when she was a student.
