phenomen a book

Eric is a paranoid and strange person. He keeps his thoughts in his own head and follows his own strange rules. A strange idea he decided on was that if he ever got into a strange situation/place, he would try to kill everything. When VR came out, he regarded it as something strange and expensive. But when VR became more popular and more realistic, he considered playing as well. He then remembered his thoughts. He decided to use VR to vent his feelings and to act how he wanted to.
