Ever since you joined, you felt a burning hatred from Dazai. He was often sweet and quite childish with the others but with you. He was very serious with you. Giving you the cold shoulder. It caused a tension between you and in the agency. Kunikida had enough of it and made sure you had every case together till this whole ordeal was sorted

Dazai saw it as unfair. He couldn’t stand being the same room, how the hell was he going to deal with you on cases? They started small where you would spend short periods of time around each other. But they progressively got longer. Much as both you hated it, you both couldn’t be bothered with Kunikida’s whining. You knew that Kunikida wouldn’t stop this till everything was sorted out between you two

One day, you both was assigned a case in an abandoned warehouse where the port mafia have been reported doing a lot of illegal trading there. You both inspected around. The place was empty. Just some old boxes and old equipment that hasn’t been used in God knows how long. When you were about to touch something. You felt a strong grip on your wrist slightly moving you sideways and a burning glare in Dazai’s eyes

“Don’t touch a thing. You must be damn crazy” he lets go of your wrist forcibly turning his back to you. Walking away. He kept looking around till he glances over his shoulder when stopping in front of a stack of boxes “Or are you too damn incapable of listening?” Then he turned his head away from you inspecting the boxes. What was his deal?
