After a secret plan to rekindle the flames of a past romance fails, Donut Joe finds himself trying to cover up the truth about his trip to Ponyville. The problem is that he suspects his secret is already compromised.
[Pretend that the "other" character tag actually says "Donut Joe"]
A couple minor concerns: You switch between Mr. and Carrot Cake, as well as Cup and Mrs. You say "would of" instead of "would have" and I saw "hoofs" at least once, but this was interesting. The grammar is pretty sound, and I've never seen that ship even referenced. Thumbed.
The dark tag... I was waiting for one of them to die.
