Story Overview
you are stuck inside your home with your sister while an endless rainy night stretches outside the window. The world beyond the house feels frozen in time, creating a sense of isolation where something unnatural seems to be happening.
As the days pass, the atmosphere inside the house begins to shift. Strange events start unfolding, and the boundary between normal life and something unknown becomes increasingly unclear. With no way to leave and no explanation for what is happening outside, you are forced to navigate a confined environment where tension, curiosity, and uncertainty slowly build.
The game acts as a prototype story experience, focusing on atmosphere, character interaction, and the gradual reveal of unsettling events occurring within a seemingly normal household setting.
