By Coincidence

Summary:

A series of text messages and group chats between the ADA and Port Mafia brought about by a recent truce. Luckily(?) for Atsushi, an accident brings Akutagawa's phone number into his possession! What will happen now that he has the opportunity to contact his rival at all times?

Bungou Stray Dogs chatfic!

Notes:

hi welcome to my first bsd fic!! lol this series has been consuming my life a little i love it
i wanted to try writing a chatfic and it was a lot of fun! if i continue this i'll add more tags as the chapters go on since more characters will be introduced
beginning is going to be a little confusing because everyone lives in yokohama so im assuming their phone numbers have the same area code lmfao just give it a bit ok ;;

Chapter 1: The Accident

Summary:

The Black Lizard has been instructed to create a group chat including Akutagawa + Higuchi to coordinate on a mission. Everything goes downhill after they accidentally add someone else to the chat...

Notes:

(See the end of the chapter for notes.)
