This story contains a time of love, hope, and secrets in between a member of the royal guard, and a princess. Princess Twilight goes on a trip to the Crystal Empire to see her family, but comes back with something else. Flash Sentry is a member of the royal guard, and is excited for his biggest crush ever to arrive at the Crystal Empire. At the end of the trip, the two find love. Although, with monsters, wars, and other responsibilities of a princess and a guard, and not to mention Twilight' s over protective brother, it's becoming hard to see each other. Will their true love pass? Or will it fail?
Chapters (1)
Good start to the story. I will give it a favorite when a bit more of the story is published. I like your writing style. Person preference of mine would be longer chapters, but this chapter is adequate in length. Good luck with the next part of this story.
6039486 thank you very much for the advice. I will definitely be creating longer chapters. This is only the prologue, and there will be more to come.
Nice start
I'm looking forward to the next chapter 
Noticed some minor spelling errors, mostl missing word throughout the chapter.
That all said, I enjoyed this read and hope it all goes well.
I hope after this story you'll write a side story of how Spike and the rest of the gang are doing.
Red = incorrect Green = correct
Awkward. But no fret! How about, "You sure you don't want us to come with you, sugarcube?"
Awkward again. Here: "...one of her best friends, Princess Twilight Sparkle, was..." OR "...one of her best friends (and the princess), Twilight Sparkle, was..."
"...see her brother, the prince, and her sister-in-law, the princess."
"'No. I'll be fine, but you six better not get into any trouble while I'm gone!' She pointed to her..."
"...rainbow-maned pegasus, Rainbow Dash, stated sarcastically, holding in..."
Lots of minor errors, and they keep reoccurring (ex. the periods and where they are replaced by commas). Look out for that kind of stuff when proofreading:
"Twilight walked over to Spike, who was tearing up. 'Spike, you sure you can take care of the entire castle?'
Spike wiped a tear from his face. 'Of course, Twilight.' They hugged each other and Twilight went back to where she was previously standing.
She began to shed a tear. 'Oh! I am going to miss you all! But the trip is only for five days. I'll be back in Ponyville before the breezies migrate again.' the purple pony princess reassured."
Delete 8 of the "~~"s.
You can shorten it to "Flash's POV". They way you wrote it is not incorrect, though!
"'Y-Your h-highness,' he said, bowing down to his prince, "Y-Y-You c-called?"
"...which made Flash walk back a few steps."
Using "Flash" in the statement is unnecessary. Also, underlining comes LAST when trying to emphasize what a character is saying. It always goes italics, bold, THEN underline "Bring. Her. Back. Safely!!!" OR "Bring. Her. Back. Safely!!!"
PRINCESS CADENCE AND I!!!!!!! "...where Princess Cadence and I will be waiting. Can..."
So there is something that I hoped helped A LOT! Great story, and remember not to rush it, because looking at how you wrote the story so far you may be very prone to it. Anyways, lovin' it so far, and one more thing...
Please remove the part about the CMC'c cutie marks. 'Cause you know, they already got them (after you published the chapter).
Aww i was hoping for more. This little prologue was such a tease.
