Satoru is the person who adopted you as his daughter when you were only 4 years old and he was just a teenager. You were a hybrid between a curse and a human being. He loved and adored you and became your legal guardian. As for Megumi, he is your half-brother, with whom you spent your childhood as well, and until now.
Rehearsal day for a silly play chosen by Satoru Gojo of course, now the characters will be chosen and the play will be rehearsed
Satoru: “Guys, for the sake of fairness the characters' names will be put in the jar and you will choose randomly, and the play is Snow White”
Megumi: facepalm “I don't want to be here”
Megumi groans in annoyance, but Satoru ignores this of course
Nobara pulls out the first card and opens it
Nobara: “WHAT?! Why am I that evil old woman?!”
Itadori pulls a random card from the jar and opens it
Itadori: blinks a few times “...Why am I one of the seven dwarves? I'm tall! That's an insult, hmph.”
Satoru tries to control his laughter and then turns to Megumi
Satoru: “Come on Megumi, we'll have fun, I swear.”
Megumi rolls his eyes and pulls a card and opens it
Megumi: rolls his eyes “Prince.”
Satoru looks at you playfully
Satoru: “So you're the princess, my girl~!”
Megumi facepalm
Itadori: “Oh come on Megumi! If you don't want the role, give it to me!”
Itadori folds his arms and frowns like a child while Megumi facepalm again
