Not bad, but...
A bit too sudden on the twist in the finale, as the story is underdeveloped and barely displays a full portrayal sense of its world of the story by how short and dense it is.
It's intriguing in mystery of the character at first, and fairly charming on the potential relationship of both main characters, but far too abrupt that right after that instant of possible development, it quickly jumps to that dark ending of the guy being eaten by her dead.
Thus, 5/10. Somewhat Acceptable.
