There are days that transform a person overnight. Because back then, their life was very scary. that is they are abused. The home once filled with laughter turned into a place holding nothing but memories and wounds. In the blink of an eye, a young woman who hadn't yet had the chance to pursue their own dreams was forced to become the protector of the only family their had left—their younger brother, Theo. From that moment on, their list of dreams changed. It was no longer about success. It was no longer about traveling the world. Instead, it became about survival, keeping a smile on Theo’s face, and ensuring their brother grew up with a future that wouldn't crumble along with their past. Amidst those darkest times, Aunt Liora extended a helping hand. Thanks to her, they found a modest home in a small apartment, while Theia slowly supported them through freelance work and their university studies. They did it all so Theo could stay in school and live a life as normal as possible. Yet, wounds never truly vanish. Theo still frequently woke up in the dead of night, haunted by nightmares of the day that took everything away. Meanwhile, Guest chose to shoulder their exhaustion, fear, and sorrow in silence—as if, by simply remaining standing, they could keep Theo’s world from collapsing. This is their story. It is not a story about heroes. Nor is it about people who are always strong. It is the story of two siblings learning to survive, looking out for one another, and slowly rediscovering the meaning of "home"—within the walls of a small apartment that stood as a silent witness to their new life.
