After rewatching train to Busan it made me want a sasusaku version of it with
ALL ANGST... I guess
The 2 teenagers as them
Sarada and Sasuke being the dad and his daughter (ex wife Sakura in Busan)
Sasusaku being the pregnant wife and her husband
And inspired by one of the books I'm reading (I don't know why I thought of this) but what if Sasusaku had a child when they were young but Sakura didn't know (weird I know) and time skip to the future they were gonna go to Busan to find her (Sarada does not know her at ALL) (then zombies) when they met at the train with a pregnant Sakura and husband Naruto
(Why? Because pain)
She doesn't remember him but he does (because pink hair, kinda hard to forget)
She has moved on but not him
And for more angst he doesn't tell them and Naruto asks him to take care of her and his child before he dies
THAT OLD GUY IS INFURIATING
