Differences between Raoul and Erik singing “All I Ask of You”
When Raoul sings it, he’s literally saying to Christine, “I know you’re going through a rough time, but please remember that you don’t have to always be by my side and make sure I’m always okay through this. As long as I know you love me, everything will turn out alright and I’ll try my best to be by your side.”
When Erik sings it, he’s saying, “Christine, you need to love me. All I’m asking is for you to love me. Is that so hard? Love me, Christine. I need you, and I deserve you.”
The differences is love and posession. While Erik is forcing Christine to love him, Raoul is telling Christine that she doesn’t need to give him affection and love all the time, she just needs to care for him.
