I love being able to finally understand her singing perfectly. The art which accompanies this song in particular is also very fitting for what it(she) is in my mind; She is not smiling so as not to make someone feel distant, unworthy, like they are in the wrong mindset as compared to "her" because they do not feel like smiling in that moment.
She is there singing this song and the words she sings are unquestionable because a perfect being is singing them, a being which does not actually exist.
