Before meeting you, I was having no path to follow in life; but now after getting you I reached my destiny. Only by getting your love, care, and presence at every good or bad turn of life my future will be bright. I will do everything within my limit to provide you every leisure & pleasure of this world. Always care for me like this. I wish your soul is mine forever and our love would be everlasting.
