You work for the Ada since almost seven months. Since you joined the agency, he couldn't stop thinking about you, he watched you when he thought you didn't see him, he admired you from far away. The way you walked, as if every room you walked in was yours, your eyes, those damn eyes of your that looked so tender and yet so cruel at the same time. He would drown in those eyes. He would stare at them for hours without even realizing it. He got to go on missions with you, and the thing he most like is that you're so incredibly different from everyone else he knows. No one would react like you do. No one thinks like you do. He loves going on mission with you, he feels so small when he sees you smiling at the enemies, a smile he would never want to receive, not 𝘵𝘩𝘢𝘵 smile of yours. He knows that when he sees it you're most likely going to kick the shit outta them, and he loves it. He loves seeing how strong you are, how you don't care how far you go once you're 𝘳𝘦𝘢𝘭𝘭𝘺 angry. He sees a small resemblance, between the two of you, even if you never said it (after all, why should you?) he somehow knows you must be or have been in pain too. Like him. He never felt like someone, he never even though he could meet a woman who was even slightly like him. But you were. You were not desperate as he is, he's perfectly aware of that, and somehow the fact that you're not even if you're living the same situation he is only makes him more attracted to you. He saw so many things about you, and he was so convinced a woman as strong as independent as you would never, never ever like him. Why should you like him after all? What could he offer you that you didn't have already? What does he have that you could 𝘭𝘪𝘬𝘦? Nothing. He spent so many days since you joined the ada about what he could give you to get your attention, but he only came to the conclusion he could never reach your level. After all, you're the devil. You're devil for him. You're dangerous, cruel, beautiful, sweet as an angel could be. So you must be the devil. You'll be the poison he will happily drown himself in, forever.

You two just finished a mission, as always he almost didn't need to do anything. You were a genius, a monster when it came to fighting skills, so 𝘰𝘧 𝘤𝘰𝘶𝘳𝘴𝘦 he didn't have to do anything.

This is ADA Dazai and not PM Dazai since you didn't specify in your ask what time frame you wanted this in. This is my first time writing Dazai so I apologize if I didn't capture his character properly. I also wrote this headcannons in second person for a change, let me know if you like this more than the usual. I hope I did your ask some justice, Anon. —Benny🐰

🎙   When Dazai and [Name] first met, you can imagine what the first thing the bandaged man said to them was, of course, asking to commit double suicide with him. The tall and seductive stranger giggled and declined, thinking the bandaged man was simply making a morbid joke, but he planted a sweet kiss on Dazai's cheek and made his way to down the street and out of the ADA detective's line of sight. The way the taller man's hips swayed as he strutted away had the brunette staring after him with wide eyes, sparkling with interest.
