If you too have ever been kidnapped by parents saying 'it's all for your own good' and manipulated your life with living expenses, this drama will deeply strike a chord with you. A pair of twin sisters lived in endless competition from childhood to adulthood. After the college entrance examination, they discovered that the living expenses promised by their parents were a scam from beginning to end. The parents are respected famous teachers, yet they treated their two daughters as samples to build their careers. The sisters, who had been hostile to each other for years, untie their misunderstandings, gather evidence, and tear off the disguise of family affection. No cheesy revenge, just holding onto the bottom line of one's own survival and walking out of a manipulated life.
