A crush that'll just hurt me in the end

We used to be friends
You, me during art class every weekend
Though I didn't notice you then
I really notice you now
During first year I started to fall
You kept me distracted through it all
Then a sophomore I became
My feelings were still the same
But the greatest thing during this time
Is that your classroom is next to mine
Now, I see you everyday
Walk around the corridor just to get close to you
Even sit near
While you're waiting for your friends to appear
Then your prom arrived
And left me as a second year
I could've expected that you'll be prom king
My dear
You were always a king to me
But only with me as your queen
I text-ed you
But with true messages unseen
Never have I gone through day
Without thinking about you
Then I found time to think it through
I will never be with you
