If you really fall in love! Doesn't it matter whether you are related by blood or not?
If you really fall in love! Does the disparity in status not matter?
If God lets us fall in love! Why are there so many thorns between us?
When everything comes back to square one, am I still the most important person in your life? Is she still your "sister"?
Is "love" between us "fate" or "evil"?
