The love for a certain dash

Ah it was a beautiful day in ponyville, actually a bit too beautiful. Twilight was in the lab working on her latest spell, it has been taking her a whole week trying to learn how to do this spell. A week ago, spike was looking in the deep ends of the library until he finally saw a dark and mysterious entryway to a book shelf with ancient books that looked like they haven't been touched in centuries! Spike took one book with a broken heart on the cover, " this doesn't look suspicious and totally going to be dangerous in the near future at tall! I should give it twilight she has been looking for something to read!" Even though the book said "read at your own risk on it" spike immediately gave the book to twilight (I mean c'mon spike I thought you were careful!) So now the young twilight sparkle is studying a spell that she has no idea what could happen when she does it (totally safe.) As twilight mumbled the words under her breat while lighting up her horn, she finally managed to do the spell! "Hmm nothing happened? What a complete waste of my time!" Spike over heard this while eating some sapphires, "maybe it just takes time for something to happen remember when you did that spell where everypony's cutie mark switched?" twilight blushed at spikes words remembering her big screw up. Spike suddenly noticed and said blushing "and now your a princess!" But that didn't make twilight feel any better. "Are you sure you did the spell correctly?" Spike questioned "yes I felt it, every time a unicorn does a spell correctly they FEEL it" spike r plied with a disappointed look on his face "blah blah blah you have told me that a million times twi! I think I have learned that by now!" Twilight rolled her eyes and continued to wait for the spell to effect something. After about 12 hours of waiting (12 hours 16 minutes and 45.36 seconds to be exact) twilight had enough, and totally gave up on the spell and took a walk outside. When she got outside (on the way to beautiful day) rainbow dash was zooming through the air and applejack was staring in awe from below. Twilight trotted her way to applejack and asked her what she was looking at "oh howdy twi! I'm looking at rainbow dash, isn't she just amazing? She is just so skilled! And her mane is always moves perfectly in the wind!" Twilight had a perplexed look on her face asking herself "wouldn't applejack be challenging her and not just sight seeing? And is she making goo goo eyes at her!?" Twilight and wanted to see for herself what was so special so she looked up and everything around her suddenly disappeared from her sight and all she could focus on was rainbow dash. It was as if hearts appeared and everything turned pink-ish as rainbow was going in slow motion as she did a hair flip (pro editing so not cliche) twilights pupils had become hearts (somehow) what was this feeling twilight had? And why did applejack feel it to!?
