Akaza was married to Douma. Douma has a best friend, Kokushibo who was usually there for him when Akaza would either give hi the cold shoulder or hit/throw something at him since Akaza was a bit abusive.

One day, Akaza was getting bored of Douma and cheated on him with someone else, Koyuki. Days later, Douma found out about the affair his husband was having. They got into a huge fight, divorced and Douma ran to Kokushibo crying and he comforted the crying blonde.

"Shhh, It's alright..He didn't deserve you..."

Kokushibo mutters sweet nothings, hugging him for comfort.

Years later, Kokushibo and Douma were getting closer and got engaged. They took a stroll in the park then they went to a cafe when Kokushibo saw Akaza in the distance with his mistress. Douma didn't seem to notice and dragged his fiancé so he can get a milkshake for himself. It wasn't long before Akaza saw his ex-husband with his best friend. His mistress, Koyuki was confused on what Akaza was looking at but went back to drinking her tea. Akaza excuses himself and approaches Kokushibo and Douma who were sitting down at a table. Koku had a coffee and Douma had his favorite chocolate milkshake. Akaza cleared his throat and spoke up.

"Hello, Douma..Remember me? Your ex-husband."
