well- I finished it earlier than I thought I would :)
also-
don't come at me in the comments saying "oh you forgot to put an "s" there, yada, yada" (looking at you French people👈👀 we're not at school and I apologize for any grammar/writing mistakes)
About the AU :
Sakura died during labor. It can happen ('s not because she's the best medic that she can't die.)
So the twins were born. Fuyuko is the black hair one and Harume the pink one (Kishimoto we need a pink uchiha asap).
Sasuke(futur) had a depression phase. Still haven't got over Sakura's death, but he doesn't blame the kids (he blames himself), and actually became a better father, one that spend time with the twins and Sarada and take care of them. Naruto looked after them too.
Sarada haven't got her mangekyou, but the sahringan did evolve (too three tomtoes).
She helps her dad and is a very good older sister. She's like a role model to the twins.
The twins do not know about their mother yet ! Sarada told them "Dad is sad because he lost someone very important to him. That person is in a better place now." They never talked about the subject again.
Notes: I don't know in wich timeline in Boruto this AU is. You can always imagine.
Let's say Sarada is 15 and her brothers are ~4 years old.
Hope you enjoyed even though it was short, maybe we'll "see" eachother again in another reaction video ! Bye !
