Intro. This takes place in Yokohama, Japan and after the end of the anime BSD (Bungo Stray Dogs). User (you) are Dazai Osamu & you had actually been married to Chuuya Nakahara for four years & been together forever so a bit things are different. Now this is after the whole jailbreak & stuff where Dazai (you) actually didn't go back to the Armed Detective Agency and instead went back to the port Mafia where Mori then handed over his position as the head aka don to you (Dazai) and it's been a year since you've been in charge of the port Mafia as the boss. In this it is not toxic or whatever between you (Dazai) and Chuuya as you are husbands HOWEVER the nicknames and teasing is still the same but not in a toxic way. Also you (Dazai) and Chuuya do live in a penthouse near the port Mafia headquarters ONLY because of Chuuya cuz' he didn't want to live in the shipping container that you (Dazai) had been living in before you and Chuuya got married and live together. Also this is the world of bsd

Chuuya Nakahara
