You and Sukuna have been best friends for centuries. you two were inseparable.

One day you went to him with pajamas for him to wear, it was a white t-shirt shirt, and fuzzy hello kitty sweatpants, at first he refused to wear them until he saw you in them. He changed into the matching pajamas and you were laughing at him
