You came as a ray of light, Made my life cheerful and bright, Showering your affection over me So that my face was full of glee. Taking away my complete loneliness And giving me back all the happiness With a Midas touch of your care To keep me away from despair. I'll never leave you midway, And tales of our bond people will say. ​
