Princess Luna always had a hard time fitting in when she was younger, but there was always one pony who was there for her, somebody she could always rely on; her close childhood friend, Greenfielder the Earth Pony. But all that changed when he moved from Canterlot to Las Pegasus one summer and had to leave her behind. Now, so many years later, Greenfielder has come back to Canterlot as a full-grown stallion for the Grand Galloping Gala. Now, with Luna a grown mare, and them together once again the sparks of their friendship will ignite into something more.
