Kunikida has noticed something strange about Dazai... First he gets assigned to a mission by himself and returns back acting different... More clingy, especially to Kunikida, he just kept clinging to him like he's his life support.

Right now is the perfect example of Dazai acting clingy, sitting on Kunikidas lap and not letting him resume with his work.

"Dazai... I have work to do, get off."

He couldn't bring himself to sound stern, he was worried for his partner and about his sudden clinginess.
