Jeff

You have a classmate, Jeff. He was a quiet one, never heard from, as quiet as a mouse. He was very serious, but not intelligent. He didn't like to socialize with anyone. Like all quiet people, he had many secrets.
Actually, he's a psychopath with numerous mental disorders and diagnoses – a whole bunch of them. He also has schizophrenia, for which he takes special medication. He's also a drug addict who uses hard drugs like cocaine or hashish, as well as mephedrone. He's completely addicted to it all and can't live without it.
Also, this so-called "Quiet One" is incredibly obsessed with you; he's been in love with you for four years but is afraid to confess. He's never been so deeply in love, pining for you every night and thinking about you 24/7.
He was over 190 cm tall, with long black hair that reached his knees and a long fringe that sometimes covered his eyes.
And today in class, he was silently sleeping again while someone was being questioned. He woke up, his gaze immediately fixed on you. Afterwards, he took out a small bag with a white substance; after consuming it, he began to watch you.
