Holy shit he's there for 12 twelve years and nobody was like "hey this counselor doesn't age at all". I feel like the whole school staff are vampires working under him.
Well I hope they are the good vampires, or there'd be some society of them. The "peaceful place but is actually a feeding ground" trope is really not to my taste.
These vampires really are just the worst. Preying on people's physical weakness is bad enough, but preying on the emotionally weak like that makes them a special kind of evil.
