After reading Steins; Gate and Your Name, I was inspired to write a book as soon as I thought that my chuunibyou hadn't burned out yet. It's about two worlds with two sides, the real world and the dream world. The real world and the dream world are both what you want to be in your heart and are completely opposite to your own personality. They are destined to meet. The protagonist Yun Jie in real life begins a wonderful journey of exchanging souls with Yun Jie in the dream world.
