She's the Apex Predator

Idk man, I was just listening to Apex Predator on a two hours loop while drawing this.

When Sakura was in Junior High, her first and second year, she wasn't with her bff Rachil, and she made two friends there. (names still undecided ). Unfortunately a rich, snobby girl that attended that school didn't like Sakura because she thought she looked prettier then her.

She brought Saku into her circle to lure her into a false sense of security.

She bribed her friends into dumping Sakura on the eighth anniversary of her known parents disappearance, the one day where she's extremely vulnerable and paranoid.

and there you go, the new clique of the school asserts their dominance by hurting her emotionally. (I mean the girl also scratched her arm and face but the teachers thought it was self inflicted because of Sakura's tendencies. )

Bet you can guess who the rich girl is.
