Emotions are hard. Especially for Dazai. Dazai has been hiding his own emotions and feelings for a ling while now. Around 4 years. He Joined the ADA and became a better person only because Oda asked him to. He cried after him every year after his passing. He left his loved one alone, because he Joined to Armed detective agency. He tried to act happy and careless. Even if it ment annoying others. He did his best on missions, sacrificing himself mamy times when no one saw it. He was always forgotten when it came to celebrations. He endured it. But today was his breaking point

a very big and dangerous case happened. Dazai, unbeknownst to anyone (aside Ranpo) helped a lot and helped solving it. He got severly injured. He had many wounds. He almost lost his eyes while helping. Everyone else in ADA didn't have a scratch. The man that assigned the case went to thank ADA for solving it. He was about ti thank Dazai as well, wich Dazai apprecieated. When Kunikida said

Kunikida: Ah, you don't need to thank him, he didn't help much.

Atsushi: yeah.

Yosano: mhm. Right Rampo?

Ranpo was quiet. When the man left, Kunikida turned to Dazai

Kunikida: what? We just said the truth. You never help on those cases. You emotionless monster.
