"Who knocks behind the forbidden door?"

Two Girls, Ami and Kania grew up in a room all their lives. As a result, they do not recognize the concept of “outside” and “inside” space. For them this world is just a kitchen and a room. They never know what the sky, the yard, even, the sun is. However, there is a difference in attitude between Ami and Kania. Kania always obeys and agrees with what she says. But Ami is easily curious. If something is forbidden she does it instead.
