Shin Hyesung has lived a quiet, peaceful, and introverted life for the past seventeen years. But after his parents decide to expand their company in New York City, Hyesung and his younger brother Junjin, are forced to move and transfer to a new elite school for the privileged. Although the reserved boy just want to pleasingly finish his senoir year, Hyesung's high school life soon becomes like an uncontrollable car driving along a bumpy road. 

From the forever-babbling wit guy Dongwan, to the cool but extremely nosy dancer Minwoo, and the silent but mysterious genius Andy, all the new people Hyesung befriends turns out to be the exact opposite of what he had wished for. Just when this messy group couldn't get any better, Hyesung suddenly develops an inexplicable attraction to the school's No.1 Heartthrob Eric Mun.
