The girl Zhenya is six years old, she has never had real friends. One day, on a dull autumn evening, returning from class, she meets a boy who changed her whole life. His name was Pasha, he was the complete opposite of Zhenya. Loud, cheerful, active - this is how his friends described him. Without him this story would not have happened. A UFO attack, a missing cat, the appearance of kittens, a move, exams, a fun birthday, school, a new addition to the family and a quarrel that almost turned into a disaster. This is what happened to them in this short year.
