Several years after returning to Equestria, Luna spends most nights isolated in her room with only her tomes and music for company. Her sister began to notice a growing sadness from her loneliness, and together with Princess Cadence they decide to try and search for a consort to cheer up the Mare of the Moon.

The commotion of this decision catches the attention of Discord, who can't help but be thrilled with the idea of "helping" his favourite two alicorns get together.
