My Evil lyrics

I can't understand The good that I do to you is my evil I forge a smile to make you smile I make you happy to hide my cry I can't understand Cause in my weeping lies Your pleasant smile I was your slave while I was tied But now I figure out my strength I'll laugh to see you cry Fey to the stars to the humble you How can I accept To be attached to your wishes And due to the vanity Remain by your side
