If you think about it, do it, no need to be polite. When a painter falls in love with a musician?
"You believe that in this world, if the destined people meet by chance many times, they can eventually become partners, hold hands and grow old together."
"Never, and never... But now it may be possible, just because I met you, my love."
"Are you willing to play the piano for me for the rest of your life and compose our love? And I am willing to draw the most beautiful picture for our love."
