Dazai should've known.
He should not have worn his ring to the office of the ADA.

Chuuya and Dazai had gotten engaged the previous night.

Dazai strolled into the ADA's office, like it was any other day, except for the fact that Dazai was humming.

He hummed and skipped like a little kid who had gotten his ice-cream or cake.

He had his hands in his coat pockets hiding the glimmering gold engagement rings.

Ranpo, took one look at him, with a single smile from Dazai knew exactly what had happened.

Dazai had worn that same smile whenever he talked about Chuuya, or Marrying Chuuya, or Anything that had to do with the love of Dazai's life.

Ranpo also saw that smile when he thought about his cute Lil' Poe.

"Ooh, I see!" Ranpo grinned and munched on his snacks.

Dazai giggled, "Do you now?"

"Girl, like it was perfect."
"Oh my god, details! Details! Later." 

"What in the ever-loving fuck are you two talking about?" Kunikida sighed and slapped Dazai upside the head.

He flinched and for a second you could see the glimmering gold on his ring finger.

"WAS THAT A RING I SAW?" Yosano whipped around with a glint in her eye.

Dazai cocked his head and kept his expression from changing, "What ring?"

"The one on your hand..." Yosano ripped his hands out of his pockets

There was no ring on Dazai's hands.

Dazai slipped his hand back into his pockets and gripped the ring.

"POCKETS!" Yosano demanded.

Dazai took his hands out and quickly slipped it into his pants and Yosano ravaged his coat's pockets.

"If he had a ring, Who would he even marry?" Atushi sat in the corner pouring tea for Fukazawa.

Kunikida huffed, "Who's stupid enough to even marry Dazai?"

a sound of a wine bottle shattering could be heard.

"Oops. Sorry." Kyoka said and cleaned up the broken glass and sangria.

Fukazawa hummed, "My money would be on Chuuya Nakahara."

Dazai laughed.

"Chibi? Nah," Dazai said like you know a liar.

"I'd agree. Weren't you two partners? Double black? Soukoku? Infamous?" Kyoko narrowed her eyes.

Dazai started to sweat.

"Well I'm partners with Kunikida and we're not married."

"And It'll stay that way," Kunikida huffed.

Dazai smiled thinking about the ring in his pants, it was solid gold with the simple engraving on the inside that read Our Secret. Chuuya's was almost the same, but two little red gems on the sides on the outside. Both were smooth to the touch and not a bump could be felt on the external surface.

Speaking of Chuuya, he was currently showing off his ring to Koyo, who was fanning herself. 

Chuuya showed literally as many people as he could, saying things like, 'look biiiitch' and 'gurl I have tea' and showed off his ring. No one asked who, either they assume or remain ignorant. Don't ask. You'll be killed. 

"MORI, LOOK AT THIS BITCH" Chuuya held out his hand.

"Congrats!" He said smiling, "I get to be the flower boy right?" 

"You're like 60-" Chuuya said in a monotone voice.

Mori gasped in fake hurt and put his hand to his chest.

"Chill it, Grandpa." Koyo snickered.

Even Elise giggled.

Akutagawa smiled, "We all know I'll be the flower boy!"

Koyo Snapped her head up, "WELL I'M BEST WOMAN OF HONOR!"  

Chuuya nodded, "Yea...I was going to ask you anyway." 
"Who do you think Dazai's will be?"

"Ranpo." Koyo nodded.

Chuuya frowned, "The one who sucked me into a book?"

"Yes him, their BFF's"

Koyo groaned, "GODDAMMIT I JUST REALIZED I LOST THE BET WITH POE! We had a bet to see who would man up and propose first; Dazai or Ranpo."

Koyo grumbled under her breath.

"Anyway when is the wedding?" Elise giggled.

'I'll let ya know."
