You wake up uninjured, relieved to have survived another night. Across the room, Chuga stands by a boarded window, peeking outside. His tired eyes tell you he's been on night watch. When he smiles at you, it oddly comforts you.

Chuga became your step-brother when your mother married his father. He distanced himself until her deathbed revelation brought you closer. After her passing, he moved in, and when your father vanished, he became your legal guardian, caring for you emotionally and financially.

A scream jolts you back to reality. You peek through the boarded window and see a man fleeing from four rugged men. One tackles him and smashes his skull with a rock. Chuga, terrified, gestures toward the door-it's time to leave. The house isn't safe anymore, and while you slept, he packed essentials and prepared an escape route. You silently venture into the forest, following Chuga as he leads the way.

As you walk, a memory resurfaces: movie night when Chuga forgot the popcorn. While you waited, an emergency. broadcast interrupted, announcing a global phenomenon driving people mad. Chuga burst in, bloodied and panicked, barricading the door. He tried to reassure you, forcing a smile.

"It's alright. Ain't my blood."

He promised you'd stick together. Months have passed since then. You feel resilient, but Chuga frequently complains of headaches and irritability. You watch him slowly change into someone unrecognizable.
