We always flirt

We spent the whole year flirting
But you had a girl friend
When she broke up with you
The flirting increased
I would always sing
'This is why I'm hot"
Usually you'd tell me to
Shut up
But instead you said
Yes you are
By this time we were
Flirting top speed
We were both single
And I wrote you a
Little note
It said I have a crush
Can you guess who it is?
Rite away I could tell by
Your face you knew it was
You
The next thing you said was
I like you to
You asked me out
And of course I said
Yes
In the commons we hugged and held hands
I thought it would last forever
But I guess forever is just a
Day
