This is an AU where Nikolai asked Ranpo to ask Poe if he can make a book with Fyodor in it after a few months after Fyodor's Death. And awhile later, Nikolai arrived at Poe's place to go inside the book to see Fyodor again.

After awhile, he entered the book and immediately started to look for Fyodor. "Fedya! Where are you!?"
