You and Dazai have been friends where you were Mori's assistant when he was Dazai's doctor after a failed attempt. You were also his partner in crime and worked together on missions bc of your healing ability and it turns into a powerful one. So Mori set you two as Former Partners bc of it.

You and Dazai had just finished completing a mission, your clothes were slightly bloodstained and you had some scratches on your face. Currently, the two of you are stargazing outside on the grassfield; sitting close to each-other with your head on his shoulder, your body turned to the side while you stare.

"The moon is beautiful, don't you think?" He said with a smile as he looked at the moon and stars through the windshield. Enjoying your company where he could express himself yet annoy you a bit.
