sasuke's modern backstory

[u/aiyootsunamii67]

i'm writing a modern au fic, and i landed on 2 different backstory options.

no. 1: sasuke's parents were killed and his brother was reported missing/had left the city for a job when he was 8. he then vows to become smarter and become a detective in the future so he can find out who murdered his parents and made itachi missing. there are some flaws with this story, 1 is that its kinda hard to imagine that 2 people could be killed in cold blood and the perpetrator roaming around free in this century, and second, i dont know much about japan but i think it will be very uncommon or even unheard of that an 8 year old is living alone on his own.

no. 2: sasuke's parents have a very messy separation (not a divorce, a separation) when he was 11, and they had already had one when he was 5, when he couldn't meet his father or grandmother at all. his parents give him a hard time about it (especially his father and his grandmother), and it makes him, well, the grouchy Sasuke we all know and adore. he has to live in 2 different houses, and he never truly feels like he belongs in either house, so he decides to study as hard as possible and earn enough money so that he can move out at the soonest, like his overachieving brother who his parents always compare him to.

i couldn't really write many details because i just started the fic and wont waste time planning an extremely detailed backstory im not going to use. so give me your suggestions, please and thank you sm.
