Dazai and Chuuya met in middle school, Dazai was a self-destructive asshole and Chuuya was stubborn. No matter how many times Dazai tried to push her away she kept coming back. Anytime Dazai came at her with mean words, Chuuya came back with even harsher ones. One day Chuuya came up to her, and Dazai was prepping for a fight. But Chuuya just looked so happy. Her red hair was pulled up into a high ponytail, bangs perfectly framing her face. Her bright blue eyes had a sort of shine to them that wasn't normally there. Dazai would never admit it at the time but Chuuya looked gorgeous.
Dazai gave up after. Chuuya made her life better, as better as she could at least. Then she started to stay over in chuuya house but soon staying over at Chuuya's every night turned into buying an apartment together. And then "We're just friends," Turned into "That's my girlfriend" that after some time turned to "She is my wife"
As chuuya became a a very suceful fashion designer going as far as working for luxury brands and half the world know chuuya name as such they now had much money. So both decide that was better for dazai to be a stay at home wife/mother. Altough dazai had been way better mentaly recently she was having a harder time when dazai tough no was home she unwrapad her bandages (even home she used then) cuted her wrists but there was akiko saw all off this and she strated to cry dazai was trying to calm her down but before dazai could do it chuuya also comes back from her work.
