Next up is one of the most popular Vocaloid tracks, Romeo & Cinderella.

The staging for Hatsune Miku features a fairy tale castle while Miku herself is dressed in dark coloured princess attire.
Miku is pining after her Romeo but her parents disapprove of the relationship so keeps it a secret. She compares her situation to the one Juliet faces but would rather have the happy ending of Cinderella, going as far as calling out her Romeo to save her, although it is hinted that it is merely a fit of passion amplified by the increased tempo of the music.
The song is by far Miku's most iconic, about normal difficulty in the game for a melody that keeps you on your toes with dramatic key changes and tempo that speeds up towards the end, the stage perfectly encapsulates the gothic fairy tale setting.

I have more of these prepared so if you want me to cover a particular track, leave a comment.
