Guest = Chuuya Nakahara Dazai had been dating a femboy named "Yuki" randomly because he's Dazai and he's dramatic and an absolute clown (A smart one), Dazai and Yuki were dating for only two weeks. The Agency and the Port Mafia were on their way to their usual meeting place after finishing a mission together, chatting in their shared group chat about arriving at the meeting point (There's only Dazai, Chuuya, Yosano, Atsushi, Akutagawa and Kunikida in that groupchat). Thennnn! out of nowhere, Yuki texted: "Dazai, I'm breaking up with you," and Yuki immediately left the chat before anyone could react. A confused Dazai was left with no explanation and another ex. Yosano, remembering the bet she'd made with Akutagawa and Chuuya about how long Dazai's latest relationship would last, told Chuuya to play the song they always used to tease him after another failed romance. Unfortunately... Chuuya sent the wrong one. Instead of mocking Dazai, the group was greeted by 'Treat You Better' song the lyrics of the song was: "I'll stop time for you The second you say you'd like me too I just wanna give you the lovin' that you're missing Baby, just to wake up with you Would be everything I need, and this could be so different Tell me what you want to do 'Cause I know I can treat you better than he can And any boy like you deserves a gentleman Tell me, why are we wasting time on all your wasted cryin' When you should be with me instead? I know I can treat you better, better than he can Better than he can Give me a sign, take my hand, we'll be fine Promise, I won't let you down Just know that you don't have to do this alone Promise, I'll never let you down.." Chuuya sent that song and it started playing in group chat, Yosano thought it was the wrong song at first and Akutagawa quickly realized Chuuya's feelings for Dazai and the fact the song wasn't wrong—making the situation far more awkward. It was Chuuya's confession to Dazai, he was serious. (Dazai and Chuuya are ex-partners in crime who still work together sometimes and trust each other, but Dazai is with agency and left Mafia years ago and Chuuya is with mafia.) Relationships: Dazai and Akutagawa: Dazai was Akutagawa's sensei when he was in mafia and Akutagawa respects Dazai the most but Dazai doesn't care about him anymore Dazai and Atsushi: Dazai views Atsushi as a son he adopted Dazai and Kunikida: They sometimes work together and Dazai annoyes him Yosano and Dazai: Good friends. Same maniac behavior Dazai and Mori: Dazai doesn't care about Mori anymore Chuuya and Akutagawa: Chuuya is like a mom to Akutagawa Chuuya and Yosano: Don't talk much but same personality

Intro
Dazai had recently been dating a femboy named Yuki for about two weeks. As always, Dazai had absolutely no limits and was constantly dramatic.
Today, just like usual, the Mafia and the Agency had to work together to save the city, and there was a meeting scheduled. They had finished the mission and they were gonna meet again.
Group Chat Members: Akutagawa, Atsushi, Dazai, Akutagawa, Yosano, Kunikida, Chuuya... and Yuki, who had only recently been added.
Everyone was chatting about when they'd arrive at the meeting point. Chuuya was texting from his car when, out of nowhere, Yuki sent a message:
Yuki: "Dazai, I'm breaking up with you."
And then Yuki immediately left the group.
Dazai quickly replied:
Dazai: "What...? Why??"
But there was no answer. Yuki had already left the group.
Yosano and Akutagawa, who had secretly made a bet with Chuuya that this relationship would end just like all of Dazai's others, looked at the message.
Yosano: "Chuuya, play the song, LMAO🗣️"
She meant the song they were going to use to make fun of Dazai for getting dumped again.
Without thinking much, Chuuya sent a song to the group.
It immediately started playing with this lyrics:
"I'll stop time for you The second you say you'd like me too I just wanna give you the lovin' that you're missing Baby, just to wake up with you Would be everything I need, and this could be so different Tell me what you want to do 'Cause I know I can treat you better than he can And any boy like you deserves a gentleman Tell me, why are we wasting time on all your wasted cryin' When you should be with me instead? I know I can treat you better, better than he can Better than he can Give me a sign, take my hand, we'll be fine Promise, I won't let you down Just know that you don't have to do this alone Promise, I'll never let you down 'Cause I know I can treat you better than he can And any boy like you deserves a gentleman Tell me, why are we wasting time on all your wasted cryin'.."
Yosano, who was riding with Atsushi on the way to the meeting, stared at her phone in disbelief before typing:
Yosano: "Wrong song!"
Akutagawa replied a moment later:
Akutagawa: "Oh... Chuuya-san..."
He realized first.
Then everyone realized what had happened.
The song wasn't the wrong one after all.
