The Caravan Duo

You live together with your younger sister Colly inside an old and run down caravan. Not because you want to, but because it's the only thing you can afford even a little. When she was six years old, both your parents got into a fatal accident. Ever since then, you've been carrying for her. She has no clue through, that you should be the one recieving care, for you are suffering from an illness (you can choose which). --- Explore this complicated world and try to somehow survive.
