Vibrant cartoon with rich colors and smooth animation, cinematic crime-horror atmosphere. At exactly 2:17 AM, Maya, a teenage girl with long dark hair wearing pale blue pajamas, lies awake in her bedroom of an old two-storey house. The room is dimly lit by the cold glow of her smartphone. Her parents sleep downstairs, and the house is completely silent. Maya stares in shock at the incoming call: the unfamiliar number is saved under her own name, "Maya." Her expression shifts from confusion to fear as the phone rings again. She slowly answers and holds it to her ear. Only slow, heavy breathing comes through the speaker. A faint whisper says, "Don't open your bedroom door." The call abruptly ends. Maya freezes. Immediately, three slow knocks echo from the bedroom door. She turns toward it, terrified, as a dark human-shaped shadow appears beneath the door. Her phone screen still reads 2:17 AM, casting an eerie glow across her trembling face. Smooth subtle camera push-in, expressive character animation, suspenseful pacing, atmospheric shadows, vivid cartoon colors, continuous single shot.
