Our unspoken vow to secrecy

I love you dear sister,
please hear me out
i am being true,
but i know you still doubt

i wish you the best
i can't help you anymore
my love cannot close close
all those open doors

apparently my compassion
cannot fill all your heart
and you are simply hopeless
you cheated in life, go back to the start

i looked up to you for so long
but now you're weak, and i am strong
you i used to want to imitate
now i avoid looking at your face

what a sinful tragedy it would be
if I myself turned out like you
how can our mother live knowing this
what is a mother to do?

now i wrap up all these questions with a simple smile
we will keep each other's secrets,
at least... for a little while
