Fanfic idea- Drunken one night stand

Prompt: Both Chuuya and Atsushi have a very good night~

Notes: So not gunna lie I have been craving a more saucy ChuuAtsu story lately and his idea kinda popped up in my head a few months ago so I decided to actually write out my thoughts as a break before I continued writing for ChuuAtsu day. 

Hope y’all like it and don’t judge me too harshly on the bad grammar lol

Actual idea- 

(For context I like to imagine that Chuuya and Atsushi have never formally met or have seen each other’s pictures, so yea they have no idea who the other is or their job) 

So the actual idea is very simple, I imagine that the point maybe during a birthday party or other special occasion Atsushi gets drunk for once. Of course everyone is having a good time and making sure things are fine but at some point while Dazai, Yosano, and Kunikida are having a drinking contest they kinda lose track of Atsushi. 

Though when they start to freak out Rampo assures them that Atsushi is fine they just go back to enjoying the party.

Coincidentally Chuuya is getting drunk at the place and meets up with drunken Atsushi. 

They actually hit it off really well while drunk. Atsushi thinks that Chuuya is unfairly pretty and wants to get to know him more and Chuuya finds Atsushi to be all around adorable with his wide pretty twilight eyes and warm smile. 

They eventually head back to Chuuya’s place and l won’t go into detail but Chuuya definitely makes that tiger purr~ 

———————————————

I imagine that Atsushi is the first to wake up and is suffering a bit from a hangover but is overall feeling an odd feeling of happiness and embarrassment at waking up in this strangers bed after doing things~ 

So like the adorable but kind man he is he goes through the trouble of making sure to get Chuuya some water and medicine to put at his bed side and starts making breakfast for the man. 

Of course he only has a bit of time before going back to work so he writes a small note and leaves it next to the medicine  for Chuuya. 

He basically says a thank you for the wonderful time they had and apologizes in that self conscious way you imagine Atsushi to do since he’s not a very “experienced” partner.  He leaves his phone number hopes with a little “hope you you don’t have a bad hangover” side note. 

Then he leaves the apartment to go to his and Kyouka’s shared apartment so he can get showered, changed, and off back to the ADA.

—————————————

Meanwhile a few hours later Chuuya wakes up with a killer headache and some very fuzzy but fun memories of being with a very beautiful man. 

Of course he looks over in his bed and as expected the guy left as is one night stand behavior. 

Though what he doesn’t expect is the thoughtful little note with medicine, or the nice little breakfast waiting for him at the table. 

Honestly this combined with the slowly growing memories of his one-night stand make’s Chuuya really want this to be more then a one time thing~ 

So he sends a few texts and Atsushi texts back~

—————————————————

This goes on for at least a couple weeks with some very nice nights until one day there is a fight that’s supposed to go down with the Port mafia and the ADA are trying to contain things before it gets too violate.

Which ends up with Chuuya and Atsushi actually meeting up with each other while working. And suffice to say both of them are shocked and didn’t expect this to happen. 

Atsushi grows worried that he’s broken some sort of rule and doesn’t want to get either the ADA or Chuuya in trouble so he tries his best to avoid Chuuya while trying to act normal (even though he’s a blushing stuttering mess when asked).

Meanwhile Chuuya is pissed at first of the thought of Atsushi taking advantage of him before he realizes that the guy had no idea about his identity and doing his best to do some sort of damage control for the both of them. 

Which is cute.

So of course Chuuya being Chuuya, instead of hiding or avoiding Atsushi just decides to flirt with Atsushi the entire time. 

Because this is a new but very adorable side to his lover that he wants to keep exploring, and he’s not afraid of the possible consequences. 

He's already decided that he wants this adorable tiger and he’s prepared fight to keep him~

For those of you who may not be too familiar with the manga, during ch39: Portrait of a Father, Akutagawa shows up, as Dazai's informant, to give Atsushi documents about who the orphanage headmaster was and what happened to him.

At that moment, Akutagawa shows an uncharacteristic clemency towards Atsushi, saying that "Atsushi's master died today", and compares this to his own relationship with Dazai.

This was a long time ago now, and a lot has happened since. The Cannibalism arc is right after this, where they are very antagonistic towards each other, and includes this scene:

Akutagawa, despite his bitterness towards Atsushi for who he is to Dazai, has seen how similar they are in this sense. Atsushi hasn't, because his gratefulness towards Dazai prevents him from seeing that Akutagawa's experience was completely different with this same person. (he's also not given any time by the narrative to wonder about it)

but then just came along chapter 122!!!

Atsushi gets to see, 1:1, the relationship between Akutagawa and Dazai. For the first time, Akutagawa is relatable to him.

And of course, at the end, Atsushi calls out the illusion as being the headmaster wearing Dazai's face because we are closing this loop! We are forcing Atsushi to see Akutagawa the same way Akutagawa has been seeing him!

April is gonna be really fun :)

Concept: Orange cat Atsushi

Aka Atsushi’s a regular tiger not a white one and that means he’s got orange cat behaviours.

Tigers don’t purr instead they chuff and as long as he’s not being actively traumatised Atsushi’s always chuffing.

Because he’s happy, happy to be with the Agency.

They find it quite soothing to hear and so whenever someone’s injured or afraid Atsushi will just curl up beside them and chuff.

Touch starved orphan that hates being left alone = clingiest little guy.

It’s something the Agency all has to get used too because they’re not really that affectionate touch wise.

Most of the time Dazai is the target because he will happily indulge him (probably because he’s also clingy as hell.)

If one tries to get away from Atsushi when he’s attached to them he will shriek until they come back.

Kunikida: Atsushi! That’s enough I have a very important meeting to get too.

Atsushi looks up at him all teary eyed.

And then Kunikida leaves carrying a very happy Atsushi with him and glares at anyone to comment.

Atsushi just likes being carried but he’ll always end up upside down and if you try and carry him properly he will jump off you.

Kenji has terrified many a person by happily walking through the streets carrying a giant happy tiger (tiger Atsushi doesn’t realise he’s a giant tiger and still demands to be carried.)

The Agency had rats once and everyone thought Atsushi might do something. No he was just on the sofa, rolled on his back and baking biscuits in the air without a care in the world.

Atsushi is easily started he will jump a foot in the air in fright if the wind blows too hard against the window. He will spend the rest of the day (or rather until he forgets what he was scared off) up on the bookshelves.

He can be bribed down with food though.

Atsushi is rarely ever still, even when he’s asleep or being carried he has to move. Ranpo gave him a fidget toy once and he played with it for 3 hours straight.

The first time Atsushi saw Chuuya floating around he tackled him midair. He then immediately lost interest when Chuuya was on the ground and thus not floating anymore.

Dazai laughed his arse off and filmed the whole thing. And then Chuuya used his ability to get Atsushi off him and then you had Atsushi spinning about like the happiest little guy.

Chuuya: There’s something wrong with this kid.

Dazai: How dare you, Atsushi is a wonderful and amaz- oh shit he’s going blue. Atsushi! Remember to breathe!

Chuuya: How the fuck do you forget how to breathe?!

Dazai: He has a lot going on okay.

one time atsushi came to the office (mayhaps after not sleeping well/at all for a few days), noticed that everyone was cooing over a cat that looked suspiciously like his tiger form and thought he was being replaced and cried himself to sleep that night

dazai: hey atsushi look at what-

atsushi, already crying: how could u

dazai:

the agency:

(on the other hand if he sees akutagawa with a cat replica of him he coos and teases — a man of duality)

(atsushi when the agency looks at someone/something like him: oh so this is what akutagawa feels like so this is heartbreak and betrayal. love nothing because everything only ends. they have found a better version i am just the prototype everyone will forget

 atsushi when akutagawa breathes in the general direction of something/someone like him: lmao what r u? obsessed with me?? are u in love with me akutagawa is that it?? ha.)

atsushi: ryuu :(

akutagawa: what

atsushi: have u seen my shirt? my favorite one? i cant find it - my jackets gone too

akutagawa, wrapped tightly in a blanket: why would i know

atsushi: i mean u borrow them every now and then-

akutagawa: i've done no such thing

atsushi:

akutagawa:

atsushi: ryuu take off the blanket

akutagawa: no

atsushi definitely does poorly in heat i feel

like he’s totally fine up to a certain point but when it gets into a heatwave he’s off his game

the first heatwave he spends at the agency he passes out during a mission and gets minor heatstroke (because atsushi has never really gotten to exist outside in heat and doesn’t know a.the symptoms of heat exhaustion and b. doesn’t like to insist on his own limits yknow he feels like a burden)

the agency gets really used to spotting the signs of heat exhaustion and heatstroke

atsushi takes to laying on the agency floor a lot during the summer (hes just like my cat fr)

okay since obviously ive gotten to into catifying atsushi i forgot he was a tiger - as u guys pointed out

this is how a beach episode would ACTUALLY play out in my head - kunikida, dazai, and atsushi focus

kunikida: are you not gonna go swimming dazai?

dazai: nope! i think today im just going to relax in the sand! maybe i'll try and drown myself later tho... what about you?

kunikida: im not swimming either

dazai: awww why not

kunikida: for some reason i dont feel safe getting in the ocean w/ u here

dazai, snickering: aww~ how could you say that~ im so hurt

atsushi, in the background, trying to secretly run away:

dazai: aww atsushi-kun why are you sneaking away

atsushi, startled: me? running away? haha... no i wouldn't

kunikida: atsushi, is everything all right? don't tell me you've decided to not participate in a company wide vacation?

atsushi: no! it's not that

dazai: you cant swim? but you fish me out all the time

atsushi: i know how to swim! i just... i don't really like water

dazai: is it becuz you're a cat?

kunikida and atsushi: he's/im a tiger

kunikida: atsushi don't tigers usually like water

atsushi: well... im not really a tiger... it's just my ability

kunikida: is it becuz dazai's here?he is a rather unsafe person to be near when you're also near wtaer

dazai: how cruel~ atsushi-kun i pinky promise i wont drown you~

atsushi:

atsushi, shyly: you really promise?

dazai, who was just joking: ?????????

kunikida, also flabbergasted: ?????????? did you think one of us would-

atsushi: no! i mean obviously not haha... but you promise...?

dazai:

kunikida:

dazai: of course! we promise not to drown you

kunikida: and to get you out of the water if you're in trouble

atsushi: oh... but didn't you not want to swim

kunikida dazai, professional dgaslighters: that never happened

atsushi: ...oh okay... then i think i'll try to swim... you'll be there?

dazai and kunikida: of course

*later*

dazai: atsushi-kun you really...

kunikida: atsushi, please, it's been 7 hours come back out

atsushi, having the time of his life, eyes sparkling, tail wagging: five more minutes!!

kunikida: you said that last time too...

dazai: atsushi-kun sure likes water

kunikida, fixing his glasses: we have to just grab him and run off quickly

dazai: ooh~ kunikida wants to kidnap someone~? how despciable

kunikida: its not kidnapping its for his own good

dazai: if that helps you sleep at night :3
