10-Faced - YM feat. GUMI
original song/vid here: [link]
The song describes the story of a girl with 10 different personalities who all fell in love with the same guy. Unfortunately, his response was "I can only love one of you!" And so begins her struggle against... herself?
This was a piece for my Vocaloid artbook last year (which sold out, btw! C: ) SO YEAH OLD ART LOL
