Every night, the black dog would growl at the baby

From that moment on, the tension in the room was unbearable. Every creak of the house, every whisper of wind through the window made Mực tense, growl, and bristle. Sơn’s heart pounded as he stared at the floor beneath the crib, unable to ignore the feeling that something was hiding there, watching, waiting.

By the seventh night, exhaustion and fear had taken hold. Sơn and Hân decided to stay awake together, sitting beside the crib, trying to convince themselves that the dog’s behavior was just instinct, a natural protective measure. But at precisely 2:13 a.m., the same ritual began. Mực leapt forward, low and rigid, growling deep and guttural. The shadow beneath the bed moved—slowly, almost deliberately. It shifted and twisted, darker than darkness itself.

Hân’s breath caught in her throat. “Sơn… do you see it?” she whispered, her hand clutching his arm. Sơn shone the flashlight directly into the black void. At first, he saw nothing. Then, a pale, glimmering hand emerged, thin and elongated, its fingers curling like roots searching for life. A cold dread shot through his body.

Without thinking, Sơn backed away, pulling the crib slightly forward, trying to create distance. The thing under the bed didn’t recoil. Instead, it hissed—a sound like boiling metal—and vanished from sight, leaving only an icy chill and the faint rustle of boxes.

Mực lunged toward the empty space, growling furiously, teeth bared. He wouldn’t leave. The dog’s instincts were correct: something sinister had made the bedroom its hiding place. Sơn grabbed his phone and dialed the police, his hands trembling. Officers arrived quickly, flashlights sweeping under the bed. But what they found made them freeze.

A hollow space had been carved beneath the floorboards, hidden perfectly under the bed frame. Inside, faint scratches and scraps of clothing indicated that something—or someone—had been living there, watching, waiting. The officers shone their lights deeper, revealing a series of tunnels that led toward the walls of the house, as if the intruder had been hiding for weeks. The chilling realization hit Sơn and Hân: the baby had never been alone. Not for a single night.

After the authorities secured the house, Mực finally relaxed, lying beside the crib, tail wagging lightly. The baby stirred, smiled in his sleep, and the room finally felt safe again. Sơn and Hân knew one truth clearly: without their black dog, they might never have discovered the nightmare lurking beneath the bed. And though the house returned to quiet, every shadow, every creak, reminded them that some dangers wait patiently… until someone notices.

The black dog remained their silent guardian, never leaving the bedroom again, as if understanding that some threats could never truly be erased—only watched.
