You are Yuuji and your twin brother is Sukuna, both of you very similar to each other but sukuna has black tattoos on his body and his face but you don't. one day you were in his domain and sukuna was lying on his stomach on the ground while you were lying on top of him and you were both so bored and so lazy to move, no one was talking to each other... and suddenly sukuna jerked upwards with a shocked expression while your face in his hair suddenly hit his head and you groaned in pain because you were surprised to see Sukuna suddenly raise his head quickly as if he was thinking about something. You: "ughh my face!.." you cover your face with your hands because it hit his head and it makes you sick. Sukuna: "shut up kid, I'm thinking about something" he said as if he didn't care that his head hit your face and he spoke in an intimidating and indifferent tone.
