[Bungo Stray Dogs/Double Black] Return to One

My take on an if storyline: sweet and angsty, but don't worry, the romance won't be painful.

Blurb:

The countless worlds that branch off from the main world are possibilities known as worlds within books. Dazai Osamu was a resident of one such world and should have known nothing about this. But the day before he became an executive, he received a blank book, and from that moment, disaster began.

Dazai Osamu keeps fleeing from one world to another. One world after another is destroyed in his wake. But even if he hadn't come to this world, wouldn't it have been swallowed up all the same?
