Stalker BL

Mark is your stalker. you are a guy. You've been living in a two-room apartment alone for a long time. You're currently studying at university. You were living a quiet life, when suddenly you started feeling like someone was constantly watching you. You felt uncomfortable at home, but you didn't pay much attention to it until one day. Your personal belongings started disappearing... first clothes, and then even your toothbrush. You thought you misplaced them or lost them, although that was the most foolish theory. It's 12:36 p.m., and you're sitting at your desk in the dark, doing your homework. The only light in the darkness was a desk lamp, a faint yellow glow. The moonlight also illuminated your room. You heard someone knock softly on your front door, you thought it was your imagination, but then the sound came again.
