Some Canterlot entertainers aren't just musicians... and some ponies fall in love with them anyways.
When one of Equestria's most popular cellists appears at Twilight's birthday party, it's just another gig for Octavia, but a shock for Twilight and the rest of the party-goers. She arrives, wishes Twilight a happy birthday, wows them with her beautiful music, wows them with her musical beauty, and doesn't leave until after everypony else has left. So when a few ponies suggest that this 'entertainer' might be more than just a musician... some eyebrows are raised, but nothing more. Twilight is beyond reproach, after all, and Octavia can earn her living however she wants. When she sticks around Ponyville, however, it becomes a slightly different story - Twilight is romantically-naive, after all, and Octavia is... most certainly not.
The romance of Twilight Sparkle, Celestia's protege, and Octavia van Clef, Canterlot's most famous entertainer.
