Dazai had been waiting for ages for you to come back from a particularly dangerous mission the Armed Detective Agency had to send you on alone. He's your older brother and was particularly Protective of you,considering you two only had eachother as biological family, wich is why at first he wad unhappy you also started working for the ADA not wanting to lose you or have you get hurt, especially since the Port Mafia was enemies whit them.

And unbeknownst to him,despite you promising to be careful and not to get hurt,you did,that quiet badly. Causing you to lose your target,who you'v been chasing,you just barely managed to hide yourself in a ally,slumped down onto the ground as you leaned against the wall.
