Soukoku Evidence [It's real and here's why]

When Dazai Was Captured

Chuuya came all the way to harass h̶i̶s̶ ̶(̶e̶x̶?̶)̶ ̶b̶o̶y̶f̶r̶i̶e̶n̶d̶ Dazai. Why would he do that? Purely out of hatred? Or perhaps he wanted to see what his ex-partner looked like after all this time.

He should have realized that Dazai won't be caught so easily if he thought about it. Unless he was so excited to see him that he forgot to think?

K̶i̶n̶K̶Y̶ (?

Chuuya also called Dazai a piece of art literally

Then there's Dazai, telling Chuuya that he has no interest to be killed and wants to commit double suicide with a beautiful lady...

...and then to remind Chuuya to act like a girl before he leaves...

Keep in mind that this is definitely not the first time Dazai asked Chuuya to do this kind of thing, judging by how "smoothly" it went. 

Chuuya is so cute what the heck! So, I'm just gonna leave this scene here...

If I were Dazai I would fall too ;-; 

Dazai purposely got himself caught to: 

1) get information from the Mafia 

2) harass Chuuya. Dude, your crush is showing.
