Great friendship begins with small things... She is a little mouse, he is a huge bear. She is a child, he is an adult.

They live in different worlds: for the inhabitants of the mouse kingdom there is nothing wilder than become friends with "the big bad bear", and his neighbors are unlikely to understand why the hobnob communicates with the mouse. But friendship and kinship are similar to the real magic. And what do conventions, difference in size, historical prejudices and cultural barriers matter to the couple?
