Shin Jaemin who lacks self-confidence and is much more timid than his peers, spends his middle school days being bullied by his classmates. If there’s any hope, it’s the new and fresh Idol group 'ROSE'. On the day of high school’s entrance, the freshman representative shows up in front of an exhausted Jaemin, who spent the previous day watching Rose’s performance videos.
That representative is 'Yu Do-Yeong', one of his favorite Rose members. And they'll involve Jae-min in very 'special' fate.
