I really don't understand why people think Chuuya was genuienly happy when Dazai left the Port Mafia.
I doubt that Harakuwa took their time to convey such a contemplating and sad expression for people to completely overlook it.
Let's not forget that Chuuya and Dazai were close. They both officially joined the mafia at 15 and had been working together since then.
These two only ever acted like actual teens when they were around each other and they even had their own code language when it came to their plans to defeat their enemies.
Chuuya was basically betrayed by the Sheep so we can expect him fearing of that happening again.
When Dazai left the Port Mafia (I'm not mad at Dazai ofc, his reasons were extremely valid), and then Mori frames Dazai as a traitor to the mafia. You can't tell me that Chuuya didn't feel hurt by this, especially since Chuuya values loyalty, he actually values loyalty to a fault if im being honest.
I personally feel that if Chuuya knew the actual reason as to why Dazai left the PM, he wouldn't have felt as betrayed.
Chuuya and Dazai did have their arguments , but the arguments were very hollow since its pretty clear they both hold a certain care for each other.
I am not saying that after Dazai left Chuuya couldn't function properly, it's obvious Chuuya wasn't a depressing mess after Dazai left. But his partner that he has known for so long to leave without a word and explanation obviously made Chuuya feel anything but happiness.
So in other words: there is a middle ground to Chuuya's feelings. He wasn't in a complete slump when Dazai left but that does not mean he was celebrating either.
Dazai was Chuuya's literal combat partner for about 4 years, it is only logical for him to feel hurt by this.
Also, can we talk about the fact that even if their dynamic was strained due to Dazai's "betrayal" their relationship stayed the same? They both still constantly tease each other, and hold empty death threats above their heads yet there still is this underlying care and trust for one another.
In the Double Black episode/chapter when they had to forcibly work together (which they hadn't done in years), and due to certain circumstances Chuuya had to use corruption, that life-risking power that only the same person that Chuuya boldly "resents" can nullify. So to simplify: In order to use corruption, he needs Dazai to nulify it and if he doesn't then Chuuya will die.
The amount of trust Chuuya still holds for Dazai even after he had left the PM just shows how significant their bond truly is.
I am not even saying this from a shipping perspective, theres so much evidence that points out how strong the partnership and connection that these two share actually is.
(I do ship them ngl, but this post isn't aimed towards romance!)
If you read all the way, thank you so very much! I hope you have an amazing day<3
