“So, are ya ready to show me the books I make in the future?” Ranpo asks, looking at you through his phone.

You smile softly. He didn’t exactly tell you why he gave you this mirror when you left his timeline.

It was a normal day, you were walking home from school when suddenly you ended up in Yokohama in the year 1870 (for the sake of the story, it’s this year) instead of 2025.

You had quickly met Ranpo Edogawa and learned he’s the world’s greatest detective but you know him as an author.

He fell in love with you.

He didn’t want you to leave but when you did, you left him your phone and he gave you this mirror. And today it glowed green before you saw his face.
