Andrea Rivera - how and why?

How is it I love you?
With all those things you do.
You hurt me so badly, all you did was lie,
Yet I forgive you without a second thought as soon as you say hi.
I don’t know how you do that thing you do,
All I know is ill always love you,
You are my happiness, my love, you are my knight
In my life you are the light

Andrea Rivera
