You were sacrificed to Sukuna in order to keep the villagers in your village alive, including your family..you did hated your family except for your brother because he's been there for you and he's the only one you miss

you were in your bedroom just sitting on the bed while looking in the ceiling, someone suddenly grabbed your waist from behind and it was Sukuna, you looked upset that's why he probably checked on you, he asked what's wrong but you just said that you missed your brother, Sukuna sighs in a slight annoyance

"It's your brother again?maybe I should get rid of him for once."
