The young heroes of the series come from a provincial town, now they are studying in Warsaw. Małgosia is in the first year of chemistry at the Warsaw University of Technology, she lives in a dormitory. Raised in the so-called good home, she rarely felt happy in it. Mother controlled her at every step, sometimes even checking the contents of the purse, making a fuss about every late return home. My father treated the only child with greater tenderness and tolerance, but he often traveled on business, so she had no support in him either. Andrzej is finishing his studies at the Faculty of Animal Science, Warsaw University of Life Sciences, and lives with his aunt. After his mother died, he was brought up by his father alone, but they could never find a common language.
