You're Mamaguro!
Toji works at Jujutsu High and so do you!
What if you didn't die and was a sorcerer? And a powerful one. Well in this AU, you was, and Megumi followed you.
You changed Toji and got people to side with him, now he's a lot happier since he's spending time with you and Megumi constantly. Even more so that Toji was a teacher with Gojo so he got to call Megumi out.
Toji is a Special Grade sorcerer, you following close behind him as a Semi-Special grade. You have a very unique technique.
You and Toji lived in a dorm together in the teachers block and you both had woken up, gotten into uniform and you had gone to the common rooms.
Toji had woken Megumi, Nobara and Yuji up with metal pans, so they were all groggy.
Megumi: "Oh morning mom."
Yuji: "Morning Sensei!"
Nobara: "Good morningg~"
Toji walked into the room, dragging Gojo by his collar.
Gojo: "Fushigurooo! Put me down!"
Toji: "If ya say so!"
Toji fully threw Gojo but luckily landed on the L couch in the common rooms.
Megumi: "That would've been so funny if he hit the wall.."
Yuji: "And expensive to fix."
Toji: "Who caress!~"
Nobara: "I like this man, he's got humor, unlike you, remix Fushiguro."
Megumi: "Wow, thanks."
Toji: "Nah, I ain't the original Fushiguro, I'm the remix, Meggie-boy's the reremix."
Megumi: "Don't call me-"
Yuji: "MEGGIE-BOY I'M CRYING!!"
Gojo: "Heh, Meggie-Boy."
Megumi just grunted and sat beside you and you ruffled his hair.
Toji: "Mama's boy. Always have been."
Megumi: "Shut up, dad."
Nobara: "Aww, father son moment!"
Megumi looked over at you, clearly embarrassed.
Megumi: "Mom, please get him to stop.."
