quicksand (Dazai X Reader)

I wish I never kissed you in my living room

“ Oooh , what's that?” Ranpo's voice appeared out of nowhere, making Atsushi jump in his chair. 

In a split second Ranpo had the box in his hands, inspecting it carefully, his glasses on as if he really needed them to see. Atsushi stayed quiet, letting the detective do his work, because he was also very curious about the box's contents. 

Ranpo's eyes grew a little wide, his grip on the box got a little tighter, and his lips twisted a little to the side, but he was not smiling, actually he was frowning as his gaze stayed on the little box. 

“ Yo… how's everyone been? Don't mind me I'm just here to leave some documents for Kunikida” 

Dazai casually entered the office with a bunch of crunched up papers on his hand, he walked as if he had no weight on his feet, but his shoulders look tense and he had his eyes closed, if he didnt had the whole office memorized he would have crashed into some chairs or desks. 

Ranpo moved his eyes from the box to Dazai's “relaxed” entrance. 

The next thing Atsushi saw was the box flying and hitting Dazai on the chest, and after that, Ranpo walked towards the bandaged detective and punched him in the face, well, at least he tried. 

The punch was weak, barely connecting to the taller detective. Ranpo is not really a fighter, he has never actually been in a fight, he has had people fight around him, protect him, defend him, but never once has he been the one to throw a punch. 

Dazai finally opened his eyes, he stared at the box on the floor with an emotionless face. 

“Dazai-san, are you okay? Ranpo-san what-” Atsushi raised his voice in confusion. He has never seen Ranpo that angry, not enough to make him get physical. 

None of the senior detectives answered. Dazai just let out a loud sigh and turned to face Ranpo at last, who was wearing an angry look on his eyes and his ears were red from the frustration, his hands still in fists. 

Dazai reached out and grabbed one of Ranpo's hands who were trembling, threatening to try and punch Dazai again, still the taller detective held his fist and touched Ranpo's thumb. 

“You have to take the thumb out or you are going to crack it, it was a good punch, but try to move your hips and shoulders when you swing, arm strength is not enough.” Dazai's voice was calm despite having been punched not a minute ago. 

Dazai let go of Ranpo's hand and took three steps back. 

“Now, try again” 

And Ranpo indeed tried again, this time the hit was harder, actually making Dazai stumble a little, but not enough to make him take a step back. Still the darkening of his cheekbone said it was a better punch than the one before. 

Atsushi stayed on his desk, standing up but unmoving. He did not know what to do or how to handle the two best detectives fighting, actually fist fighting in the middle of the office for something he did not understand and was too afraid to ask. 

“Um… what is going on?” 

Kenji and the young woman were standing in the doorway, she was looking confused having read all the signs that there was a conflict between Ranpo and Dazai, and Kenji was already distracted with something so he paid no attention to the fight right in front of him. 

“Someone delivered a little box, and Ranpo saw it and then threw it at Dazai and proceed to punch Dazai, but it was not a good punch so Dazai taught him how and got punched again, and honestly I don't know what is going on-” Before anyone could answer, Atsushi was already word vomiting on the scene.
