I just cracked out this video in a few hours, hence the crappiness, but it was fun to make. :D
The lyrics explain the situation, but for people who like to know the back story, it's just basically that Selena is in love with Demi but Demi is kind of oblivious. It's a cute & pretty slow paced song, so I felt there shouldn't be too many effects. Anyways, enjoy!
ETA: The song is 'Trouble' by NeverShoutNever. Great guy, you should take a listen to all his songs. I don't know where to download it hahaha..I just ripped the mp3 from a YouTube video that had the song in it.
