"
birthday
It all began with a simple
Confession
You had an urge to kiss me and
I was on the verge to miss you
And then it happen,
No
We didn't understand
No
I won't even budge
Before we didn't hang out much
So save me in your playlist
So,
You wont forget this
When things don't quite go your way
You'll still have me on
The first person is talking about how once they confessed their love for the other, they found they felt the same about each other. Now the lyricist is saying "don't forget about me".
