The Delinquent's Pure Love

"Eugene, a model student who dreamed of entering medical school, lost her pace after a brief high school romance and failed her entrance exams. While she is retaking the exams (as a 'bansu' student), her delinquent ex-boyfriend, Junha, suddenly reappears in front of her. Is he here to ruin her exams once again? Or is it genuine lingering feelings? A se** campus rom-com about two people who are so different, they can't help but be attracted to one another."
