when we cross paths again. chuuya x Dazai smut 16+ (slowburn)

what are you staring at chuuya?

Dazai and chuuya have been partners for quite a while now, usually when there not alone together they like to hangout around tachihara, gin and akutagawa. Today however, Dazai, chuuya and tachihara have been forced by Mori to file all of the paperwork from there previous mission. Dazai groaned at the idea of doing paperwork in a small room, especially since a particular ginger with a short temper would be be accompanying him. Tachihara listened as the two of his comrades bickered at each other the entire way to the office, this was normal. But fuck it was annoying. Once they got situated and everyone was in they're own corner of the room they began working. 1 hour, 2 hours then 3 hours. Tachihara was gonna lose his mind if one more argument broke out. Everytime chuuya would even so much as cough Dazai would make a remark, chuuya would fire back and a whole argument would break out. "Would you two shut the fuck up"  tachihara finally protested, but to no avail, they didn't stop. After a few more minutes of this never ending argument chuuya finally decided to ignore Dazais taunts and remarks and focus on his work. The brunette finally shut up and followed along and began slowly but surely doing his work as well. What Dazai didn't know was that chuuya would sneak little glances at him while he was focused on his papers, chuuya ment no harm by this but he simply couldn't help it. After all Dazai is chuuya's work partner. But what Dazai didn't know was that the ginger that he works with every day and every night....had developed feelings for him. Dazai never noticed chuuyas feelings however, he always chalked it up to "we're just work partners". As chuuya snuck another glance at Dazai for the 5th or 6th time, tachihara happened to catch on. "What are you staring at chuuya?". Tachihara asked it a slightly confused tone. "Nothing you damn idiot". Chuuya fired back. Tachihara quickly backed off of chuuyas case, not wanting to anger the ginger even more and risk another fight breaking out between Dazai and chuuya again. But tachihara couldn't help but follow chuuyas gaze once or twice, he figured out fairly quickly that chuuya wasn't looking at just "nothing", he was looking directly at Dazai....all of Dazai.
