I just finished watching the movie

Overall, the plot was original. You should label it 18+ though.
I will go on with a few pros and cons that I noticed during my watch time (I watched it twice to be sure)
Pros
The soundtrack is on spot, I like that
The plot is original - I like how you used the old vcr cassette to tell some of the story - the edit is also on spot. One question...since that character died in 2014, meaning the content on the cassette is filmed after 2014, why did they not just use a smartphone or a modern camera to film it?

Maybe modify the plot from 2014 to 2004 and it is more natural then from this perspective
The costumes are very good as well - and the building from minute 12 is huge
You managed to show the girl's fate without getting so much into what actually happened to her - the expression on her lover's face tells so much emotion
The actors are doing their part very good, too
Cons
At minute 10:21, the syringe had no needle (I looked twice and stopped to check) and then he puts the content of the syringe in her neck. Maybe put a needle for the close up and then try another angle and get rid of the needle for the next part

The night scenes are a bit blurry, especially at minute 3 and 4. Maybe try using an external light or a powerful flash light for a better quality
