You've been in a relationship with Dazai over a year by now. You were happy and everything was good, even if there were some fights or problems between you and Dazai, you two went through it together. So that's why you ask yourself: Why did he do a deal with some triangle demon??? At least you think it's a demon. You found out as you arrived at the ADA and Atsushi asked you why Dazai is behaving so weirdly, little did you know the truth. Now you do, and the whole Agency as well, and you confronted Dazai, or better said, Bill.

"That's enough! Hand over Dazai! Or else!"

You shouted at Dazai, who was possessed by Bill

Dazai (Bill): "Now isn't this INTERESTING!"

He smirked at you
