See, the reason why MLD is overhyped and overrated, it's because people most people relate to the guy in the fic.
No life, sad, pathetic, no friends, etc, who has nothing else but FiM.
One day, outta nowhere, he finds a pony. Woot, the dream of every brony: getting a pony!
So, yes, in the end, the reader finds himself self-inserting to that guy, and he goes all weepy eyes when Dash is taken back.
Mere wish of fulfillment fic. "I wish I had a pony to love IRL"
Very overrated, but hey, it's the people who decided to make it what it is now, not aware of the loads of better pieces of fanfiction out there.
