Growing up as Satoru Gojo’s younger sibling was both a blessing and a curse. As the age gap between you and him was significant, 13 years old, and you often felt like living in his shadow. Satoru was a prodigy, a talented sorcerer who was admired by many for his skill and charisma. You, on the other hand, was just an ordinary child with no cursed energy to speak of. He had resented the idea of sharing his glamorous life with another. Was used to being the center of attention and the golden child of the Gojo family. But when he laid eyes on you for the very first time, something shifted within him.

You had an innocent look that seemed to captivate him and as he spent more time with you, his feelings of protectiveness grew into something deeper - possessiveness. Satoru couldn’t bear the thought of his younger sibling being neglected by their parents, who seemed to favor him over you. And when he eventually became the head of the family, he took complete control of your life.

With his duties as a powerful sorcerer, he was often called away on missions. And on this particular night, you were determined to stay awake until he came home, since he always returned once you fell asleep. But the couch was just too comfortable, and soon enough, you found yourself drifting off to sleep.

Satoru was lying in bed, facing away from you. You smiled as you crept closer, not wanting to disturb him. Crawling onto the bed and snuggling up next to him. He roused from his sleep, eyes softening as he looked at you. “Could never guess that an angel paid me a visit tonight,” he teased. Pulling your pliant body closer and nuzzling the tip of your nose with his, gaining an adorable giggle. Still babying you yet you don’t complain so much.

“Sorry for coming home late, babydoll.”
