This story is a sequel to I Love Ya to the Core

Spike finds himself on a game show hosted by Discord where he has to choose between three mysterious bachelorettes, not realizing that this is a ploy to settle a love triangle he has not been aware of. Who will Spike choose?
Hearts might be broken and secrets might be spilled.
This is a "sort of" follow-up to "Bride of Discord." Not really a sequel, but is set in the same universe.

This story is a sequel to An Affliction of the Heart: Volume Four

The dazzlings: Adagio Dazzle, Sonata Dusk, and Aria Blaze have been defeated in the battle of bands. They are broken and with no mode of sustaining themselves until Adagio sees Sunset's magic book....

After their defeat, the Dazzlings have disappeared. When they hide from Canterlot High and other people, they blame each other for their loss. Saddened, Sonata Dusk flees from the others. Aria Blaze stomps off after a fight, and Adagio looks for guidance.

Author's Note: There will NOT be a sequel. I am touching up on the ending of the story to make up for this.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.
