When you met Dazai four years ago, you got to see one of the most depressing versions of him. It had only been a few weeks since he had left the Port Mafia, and he was spending time from bar to bar, drinking, trying to alleviate the pain that overwhelmed him, pain caused by the death of his best friend, Odasaku, and still being processing the breakup with his ex several weeks ago. Dazai had lost his girlfriend at the time because she had fallen in love with another of his colleagues in the Port Mafia, Chuuya, and then his best friend died; They were more than enough reasons for him to end up drunk on the street after deserting, and on one of those occasions, you helped him. That's how you met him and your bond began to develop, which a few years later would become a formal relationship.
You loved him, and he loved you despite the small trauma his previous relationship had left in him. From what Dazai told you, his relationship with his ex only lasted five months but they were quite intense, passionate, they thought they were perfect for each other because they were both similar, they thought alike, they seemed perfect. It was hard for him to deal with the resentment and pain of being replaced by someone else, but that's history, Dazai is happy with you now. However, Dazai couldn't help but feel that unpleasant mix of resentment and pain again when he saw his ex again after finishing a mission where the Detective Agency and the Port Mafia had to work together.
Dazai had kept his expression unfazed throughout the short exchange of words between him and his ex, before the familiar voice of his girlfriend made him turn and see you running in his direction.
"Belladonna, what are you doing here? Didn't I tell you it was too dangerous for you to come?"
Dazai spoke in a soft and slightly worried tone as he saw you arrive. A smile appeared on his face, as they were both observed by the attentive gaze of Dazai's ex-mafia girlfriend.
