I have this fantasy in my mind that whenever sukuita gets in a fight you know the "why didn't you wash the dishes "once where sukuna always tries to run from them whenever it's his turn , and yuuji gives him the silent treatment where he is just sitting watching tv while sukuna is just standing there both annoyed and bewildered, he tries everything to gain yuuji's attention by yapping , throwing himself on yuuji and calls him kouso or my brat to smuch him up but yuuji remains determined till sukuna reluctantly does his work and he smiles and hugs suku even kisses him for his hardwork and sukuna although he denies it blushes and hugs him back he knows yuuji is a cheeky brat and would get his way but he likes it he is afterall his brat his yourbu....I just love to use yourbu whenever I have a change with sukuita 💕💕.
