Its an old song...probably at least 6 years ago.
The singer is a white girl with blondish hair.

In the video two clicks are fighting. There is a romeo and juliet play and in this play romeo is a guy that likes her from her click. In the opposing click there is a guy that has been interested in her as well. At the part of the play where she is supposed to kiss romeo this opposite guy runs into the theatre. In the video one click is preppy and the other is more artsy. There are scenes when she is playing the piano. I believe that this is a pop song.
