Kim Junsu and Zhang Li Yin are both players of Seoul Academy. They both planned to use each other to get even more popular than they already are by dating each other. Will this fake relationship lead to nothing? Or into love?

It was a bad day, an unlucky day perhaps. The day I had thought that would change my life forever. Sadly, it did, it changed my life, the way I lived and the way I interacted with the world. The events that occured played back in my mind over and over again. They were clear as if they happened yesterday. I will never forgive myself for being a blind and a selfish girlfriend, never.
