For Izumi Nogami, everything but herself and her friends is nothing more than a toy. Trampling on the dignity of a person and seeing a desperate face is the most enjoyable thing, and of course Akitaka Tazaki is one of those toys. She gave Tasaki humiliation and despair, so she was Izumi who kept committing him every day trying to get pregnant with Tasaki's baby, but she felt strange that she was stacking up with Tasaki. I was supposed to hold it. One day, she happens to discover Tasaki's diary notebook, and Izumi finds out that she is being manipulated by Tasaki's art.
