Soen na Osananajimi to Isekai de wa Kekkon Shite Iru Yume wo Mita ga, Sorekara Osananajimi no Yousu

“Let say it! I hate a situation where a childhood friend is defeated!”

My childhood friend “Kanzaki Amane” who I used to play with when we were kids. She and I naturally drifted apart just because she was the opposite sex……. When I got to high school, I realized she was beautiful and bright. She has excellent grades, athletics, and has become so high up in the world that she can’t even say that she’s my childhood friend now.
Amachi Yumeji watches her from afar, but one day he comes across a mysterious book that can control dreams.

At first, I enjoyed dreaming about all kinds of things that I liked, following my desires. As a result of the “dream”, Amane, who was supposed to be estranged from me, began to break into my room through the window………… Are? Isn’t this a dream?
