Disney(ish) fan versions of "What is This Feeling" by Idina Menzel and Kristen Chenoweth (from Wicked)
Wicked, the book and musical that tells the story of the Wicked Witch of the West, from the Wizard of Oz, focuses very strongly on the witch, Elphaba, and the Good Witch of the North, Galinda. It's widely considered that they're practically canon as a pairing.
And when we have songs like this one, where simply switching the word "loathing" for "lov(ing)" works perfectly, it's very, very easy to see why.
