Kiss/love/flat

[Verse 1]
My first crush happened when I was 5
So I gave him a glittered valentine
He laughed and proved why a crush is a crush
I cried all the way home on the bus

[Verse 2]
My first kiss happened at the top of the stairs
Near the lockers and the science layer
He pulled me in with such a rush
I'm going to miss my bus

[Verse 3]
My first love fell pretty flat
After some time I didn't want to deal with that
It became more of an obligation and a fuss
Like how I almost my bus
