On her 19th birthday, Jessica Jung was dared by her friends to kiss the hot guy across the street. Being the reigning champion of the truth or dare game, how could she refuse? After all, she'll never see him again right? However two days later, she finds out the guy she kissed was Lee Donghae, her school's rival's resident bad boy. If it isn't bad enough, it turns out Donghae is apparently on the lookout for the random girl who had kissed him on the street 48 hours ago. When she and her friends transfered to his school for an art programme, things get a whole lot worse. Throw in a group of insane friends, an overprotective brother, a potential boyfriend on the football team and a gang rivalry and Jessica's nineteenth year of life is already turning out to be more eventful than she ever could have imagined.
