Maya stayed late in the school art room, finishing a poster for the annual wellness fair. Students had been asked to use colors to represent their emotions, and at first, Maya thought the assignment was childish. But one deep red shape caught her attention. It reminded her of her father’s old workshop and the bright red toolbox he always carried. Her father had disappeared three years earlier, leaving behind more questions than answers.

Curious, Maya scraped away some paint and discovered a small black key hidden underneath. It looked exactly like the key that had once hung beside her father’s workbench. He had always warned her never to touch it, telling her, **“Some doors are better left closed.”** Maya traced the key with a pencil, and a tiny green door appeared beside it.

The door reminded Maya of her grandmother’s abandoned house. She searched old photographs and found one taken shortly before her father disappeared. In the background stood the same green door, with his red toolbox nearby. Then an unknown number sent her a chilling message: **“You finally found the colors, Maya.”** A second message followed: **“Go to the house before midnight.”**

Despite her fear, Maya hurried to the abandoned house with the poster and the mysterious key. The green door was still there. She inserted the key into the lock, and it turned with a soft click. Inside was a narrow room filled with old paintings. Every painting contained the same strange colors—red, blue, green, black, and yellow.

Maya stepped deeper into the room and froze. On the wall, she saw her father’s handwriting. Whatever secret had caused his disappearance three years earlier was finally beginning to reveal itself.
