Guy staring at me when I was dressed up?

So this guy at my school, 2 years ago, I liked him then he figured it out and ignored me.

and on Friday I went to the school and I was really dressed up and looked pretty.

And he just could not stop staring at me...

Was he staring at me because I looked different? or he saw something attractive in me?
