Isekaing into Equestria is impossible. Magic isn't real. Even if it was, why would you specifically go into *Equestria* of all places?
If you ever ended up in Equestria, that's already a huge heap of wish fulfillment. And unless the universe/whatever force that transported you thinks you _need_ to learn a lesson of some sort (and it won't necessarily be about avoiding parasociality or such - since one, it's not inherently bad and two, it'd probably blueball you from going to Equestria in the first place and offer something else if it were to take action) then it is not much of a stretch to say that X pony will most likely trend towards liking you back, too.
Or in slightly more likely route of building CelestAI or whatever, you upload and X probably likes you back if that's really what you want in your heart of hearts.
Anyway, if I were to wake up in Equestria I wouldn't really assume they'd like me - it's not right to treat people like that. It makes me very sad, but I'm sure the feelings would pass. Would just try to avoid them and become a wizard or something.
I like Twilight a lot. I'm not good enough for her or most other ponies. It'd be cruel and wrong to impose myself on her, even if she somehow reciprocated. That's just how the dice came out.
