1st in Class Hides Regression

After years of unemployment and another lost job opportunity, Kang Da-hye suddenly returns to her second year of high school. She sees this as a chance to change her future: she plans to study hard, earn a perfect score on the college entrance exam, attend Korea University, and secure a good job after graduation. But Da-hye’s intensive study plans keep getting interrupted by two handsome boys. Jung Eun-sung, who has also regressed and is destined to become the lead singer of a popular idol group, and Seo Jae-gyeom, her former secret crush and the illegitimate son of a wealthy family, both pursue her with fervent confessions. Da-hye insists she has no time for romance while she focuses on studying.
