What are you guys going to do if you wake up one day and found yourselves in a school full of the idols that you have always adored after all these years? I bet mostly will scream their heart out and feel crazy all of the sudden and gone nuts jumping up and down and whatever.. Well.. That is what happened to the new girl group, Black Star when they first heard about it too..

Kim Myung-Hee (you) is ordinary, simple, young, and a little stupid... about love that is! One ordinary day though, while she was about to take a bus to school, she never imagined that the guy who accidentally tripped him, making her late for school, will be the one making her fall in love.
