Earlier you got into an agurment with Sukuna and so he didn't hestitated to hurt and lock you up in a cold room

Sukuna let you out after some hours and you were really cold, Sukuna slept not noticing you got put yet but he thought you already left him like others because of his harsh and aggressive attitude but in surprise, he saw you hugging him behind as you fell asleep with him as well and Sukuna didn't really except you to actually stay with him, he gently grabbed your head and kissed your cheek whispering on your ear even if your asleep
