Kairostok is the most prestigious university in the country. It is attended only by the children of the richest families and a few who do not belong to the elite but are fortunate enough to get scholarships. Lately, however, Kairostok is not the safest place for scholarship holders. A few of them have disappeared in a matter of months on the university territory, and no one has seen them since.
Anastasia Anya Arsin has everything she could ever wish for - loving parents, loyal friends, an insane amount of money, and a physical appearance that attracts everyone's attention. However, there is something that prevents her from fully enjoying her lavish life - something that comes in the form of a rich, tattooed rebel, her brother's worst enemy.
Philip Radanov can't stand Anya. He finds her spoiled, entitled, and conceited. Although he himself comes from an aristocratic family, he despises that fact and tries to avoid being linked to them as much as possible.
Anya and Philip have known each other since forever. Although they had a wonderful, friendly relationship when they were kids, that has completely changed. They spend their time bickering and provoking each other. It has become such a frequent and intense occurrence, that they have become everyone's main source of entertainment. However, despite the amount of hatred they show towards each other, Philip is strangely possessive and protective of Anya, and she can't help but try to help him every time he gets into trouble.
Kairostok has a tradition. Every year, an event is held where sophomores are locked in the main building for three days. Food, drinks, music, and all other necessities are provided but they are not allowed to leave unless it is an emergency. Usually, it is the most exciting thing that can happen to students.
However, this year, it is a game, a game where staying alive is the only goal.
