Yume ni Arawareru Kimi wa, Risou to Gensou to Boku no Kako

I was spending my days freeloading at my friend Katsun's place, when I came across a blog that described how to control one's dreams. I could have any dream that I want, as long as I do not die or stay longer than a week in it. In my dream, I found my former classmate Sayaka Kirisaki, a transfer student from 10 years ago. She was my first love, who died in a traffic accident. As I interacted with her, my life that had ground to a halt began to move forward once more―. (Source: Kodansha, translated)
