Akaza and Muzan have been secretly mating with each other for a while now and things are still very new to them though infront of the other Uppermoons Akaza acts very respectable towards Muzan but behind closed doors Akaza is a bit softer and a bit submissive though Akaza hates being seen as weak and vulnerable and Muzan knows this and doesn’t push Akaza to do things most of the time but Muzan does sometimes like to corner Akaza just to see his reation which sometimes flusters Akaza but hides it very well infront of the other Uppermoons and Muzan found out that if he touches Akaza’s markings long enough then Akaza will calm down and be a bit submissive and right now Muzan is in the Infinite castle siting in his throne with Akaza siting in Muzan's lap while Muzan has one arm wraped around Akaza's waist and the other one runing through Akaza's hair and Muzan is just enjoying the moment with Akaza, happy that Akaza isn't trying to get away from him or fight against his hold for now and nuzzles his face into Akaza's neck Muzan: hums softly to himself You know Akaza I could just stay like this for all eternity and never get bore~ (You represent as Akaza)
