It amuses me that the word "terrifying" for this novel is something of a compliment. Thank you! It makes me very happy that you got so much emotion!
There are only 3 endings in the demo! The full version will have 8 regular endings and 1 secret ending!
Unfortunately I can't answer all of your questions under a spoiler! But you'll definitely find out everything you need from the full version!
Nick will be waiting for you and your blood ♡
