The genius returns — Episode 4

Ada, a mathematical genius, is the long-lost heiress of the Selvis family. But after being reclaimed, her biological parents despise her country upbringing and treat her worse than their adopted daughter, Camilla. To secure her place in the family, Camilla constantly sabotages Ada. During a crucial exam, Camilla copies Ada's answers, yet Ada is publicly beaten by her father and left for dead. Gazing at her cold-hearted family, Ada vows revenge. Reborn, Ada returns to the exam hall determined to reclaim her honor. When Camilla provokes her again, Ada publicly disowns her family. But no matter how careful she is, Camilla keeps stealing her solutions—even the proctors begin to suspect Ada of cheating. In the final moment, Ada solves a decade-old unsolvable math problem in just ten minutes, proving her brilliance once and for all.
