I agree with what most of the people here say. It's too much plot for too little space. I am not sure if you are capable of writting a dark story but I haven't seen your writting just your idea.
Quote from Klapzi
Let's start with....Your plot is an abomination(a mix of Twilight, Vampire Academy and The Sword of Truth)
The whys:
You have a big plot ideia and are trying to condensate it into a few days. A short story plot must be simple, read books for children and you will notice it.
You are not mentally capable of writing a dark story. No, I'm not saying you are dumb, you are just not the kind of person who writes a dark story... You are probably a happy high school girl(at most) who reads shoujo, you should write love stories.
The guy is called Edward.
The protagonist's sister is a ridiculous character in many ways, but I guess this is part of the dark mentality thing.
No parties on friday.
The idea itself sounds like a combination of various plots and it isn't very realistic.
For example
-The time frame is much too short for the amount of thing happening.
-If the boyfriend turns into a jerk there would be tip offs. Not large ones but maybe he said something that makes you a little uncomfortable. Even if you did like him, you would have this nagging feeling in your stomach. (Been there, done that)
-Moving into someones house isn't very sudden. You need to put the house on the market, pack and move your things, inform the government and various other things. Not a short process. The shortest amount of times is maybe 3 weeks.
-There need to be a better motive for her sisters hate for her. Jelousy IS a major motive but for a 10 year old it's stretching it but if she had a more unstable childhood then her sister or major event that happened to her only, maybe a dehabilitating or tramatic accident it would make a bit more sense.
-Edwards character seems very 2 dimetional. Does he have a background of mental stability issues? What did Alice do to make him love her. Did he have a tramatic past or is she the only one to understand him? Abandonment issues perhaps where people are taking away "his" Alice? I know he loves Alice but killing someone is a bit far especially with no prerequisites of previous violence. If he has been over protective of her to begin with then that part might be a bit moe believable but you stated that he ignores her in class so that can't be possible.
-The whole orphanage thing isn't very realistic for the exact reasons Hespia Klarerin stated below.
The names do sound like Twilight names and it makes me cringe.
Quote from Hespia Klarerin
what wait
so alice is this beautiful girl that was born from alcohol-abusing mom and have a sinister sister
and her boyfriend is a obsessed psychotic murderer that murdered her sister and her step-dad
and she still chooses to love him
is this a case of Stockholm syndrome?
ps. where does she live that she ended up in orphanage because her mom can't take care of her. certainly not in America in 20th century. first of all there isn't many orphanages out there, they're replaced with foster homes. and if her mom is so poor that she can't feed her own daughter (which makes no sense since she must've had some money leftover from selling her house, not to mention that her husband died, so she should've got inheritance) there are programs out there that helps children (under 18) in poor home. basically, government give u money! (but of course, is her mom abused her kids in her alcoholic condition, then social workers will take the children away to foster home)
To what was said earlier about writting a short story, I wrote a short story for grade 8 about a girl who cuts herself and it was very graphic and realistic that 2 teachers, school nurse and principal called home to ask my mother if i had household problems and offered to give me "help". The next day the whole class had to have wrist checks to see if anyone was cutting themselves.....
