He loves shoujo manga and cute idols!

Mutsuki is a designer who cherishes his otaku hobbies but lives a life without much contact with others. One day, he meets Seki, a god who has run away from home for some reason.

Seki was so impressed by the first volume of a bible-like shoujo manga that Mutsuki had left behind near a shrine years ago, that he has been longing for the next volume ever since. Surprised by Mutsuki's unexpected hobby, he makes Seki read the rest of the book at his house, and afterwards they have a blast talking about otaku things...!

With that in mind, it might be fun to have a fellow otaku nearby...?

Thinking this, Mutsuki decides to let Seki, who has run away from home and has nowhere to go, stay with him, but...?
