HELP PLS

Guys is this Monologue (as a villian) okay? I need to improve it, are there any problems or tips you have to make this better?

"Allow me to introduce myself, you probably don't even remember me, 2014 hero expo. Does it ring any bells. I was 13 and your biggest fan, all I wanted was one signature but you left me and multiple others in the queue without getting the opportunity meet you. It was probably a long day for you but for me it was my only day to even see you, yet you left. Ever since that night I had studied your every move all your friends, the bars you go to, the time you sleep. All comes down to this one moment where I make you feel the pain."​
