Writing style read too much like fanfic- really basic descriptions (ergo no ambiance) and characters had no distinct voice. All POVs read the same. Took no time to establish normalcy and once things started happening, they seemed to happen at random. Couldn't engage with story without wanting to fix it. 

Also, romance was almost entirely sexual and there was no established chemistry beyond They Fucked. Came off extremely fetishizing. Don't really think a spooky voice sexually harassing someone counts towards scary.
