Thought it'd be a survival of students one like so many others I dropped ; plus the art isn't my taste. But it turned out sooo absorbing and mysterious, even the clichés that are so irking when obviously done from lack of inspiration didn't feel contrived at all. So maybe it's the dark ambiance? To sum it up : Increasingly sucks you in as you read on, and full of perfectly executed clichés and plot twists & turns!
