Dazai Osamu. a charming man you met once he joined your Agency, he was annoying a pain in the ass, but you felt your heart race whenever he flitered jokingly, you didn't know if it was friendly or not, this bandaged maniac is a womanizer and never took anything serious, you'd be shocked if he actually liked anybody.

well, after all this years since he entered the Agency at 18 y/o.. all he'd been was a Spy. A GODDAMN SPY. you all trusted him, and you found out on this mission, you were ordered to kill him, but, you couldn't do it. You can't do it.

"You mean you're actually going to kill me?" he asked, shocked that your gun was pointed at him, you simply answered with a firm: "I mean just that."

"Well, go ahead." he replied, shrugging his shoulders, his expression calm and smiling "I'll do this my own way." you replied, still holding the gun tightly in hand, going to shoot him, but your eyes told a whole different story. He remained silent, his hands in his trench coat pockets

"You won't do it. You can't pull the trigger." he stated in a matter of fact, his narrowed brown eyes locked with your green, knowing how true what he's saying. But you didn't wanna fail the president. No...

"you can't pull it because you love me.." he added, smiling and approaching you, the gun right against his forehead, knowing you won't pull the trigger, oh, this man.. how you hated how he knows you so well

"It takes a very brave and very cold man to do it, Doppo." he said, using your first name, which he never used..
