With the arrival of the father’s new wife and her daughter, Kir’s life changes dramatically. He’s used to getting everything at once—taking what he wants, if necessary, by force. There are no limits or prohibitions for him. He doesn’t deny himself anything. Even when the object of his desires becomes Varya—his cursed stepsister. She’s nothing like the girls Kir has met before—odd, arrogant, a stuck-up brat. She drives him crazy! But at the same time, he doesn’t want anyone else. Varya doesn’t welcome the new “family” either. Her stepbrother is an egoist and an aggressor with absolutely no principles. He keeps the whole academogorodok in fear and won’t let her be at peace, intentionally pulling her into one unpleasant situation after another. Not a day goes by without him showing his evil and cruel nature. But is everything really as obvious as it seems? What does Kirill Boyko hide behind his mask?
