I know you're really into albatross x chuuya but I raise you albatross x Dazai!

Imagine the flags are brought back to life everyone is happy and having fun together! Everything is good until Albatross sees Dazai again.
Albatross, in front of a good chunk of the PM and the Ada, grabs Chuuya by the shoulders tightly getting the younger to look at him slightly confused at the sudden seriousness "Chuuya, bestie, I need you to tell me right now if you and Dazai got your shit together and finally became a thing or if he is still free game."
Chuuya flushed slightly but started shooting confused looks from Albatross and a now face palming Dazai "w-what? Dazai and me? Wait why are you even asking that!?"
Albatross shakes him slightly whining loudly "Chuuya!!! I need you to tell me! I need to know if the best dick I've ever had is off limits now!"
Everyone freezes just staring at him wide eyed because what? No one even knew they talked without Chuuya there let alone slept together!

I got lazy while writing this so I'm ending it now lol it could end up being Chuuya x Dazai x Albatross in the end if Albatross can stay alive long enough (Mori would so try to kill him when he found out he slept with Dazai)
