The song, in sum, is about a speaker who is very in love. Through the use of figurative language such as hyperbole and metaphor, the speaker is able to relay to the readers that the love they feel is understandably new. The speaker compares his trance of love to specialty cakes and sweetness. The connotations of the word "sugar" and "sweet" bring the idea of addictiveness to the reader. Much of the time, anything sweet and sugary is desirable and addictive to a human, much like how to speaker is feeling about his new found love. He is so addicted that he doesn't want to lose it; the thought of it makes him hyperbolically weak and broken. Overall, the theme is shown through the metaphors and hyperboles and really is just saying that many times, humans are addicted to the idea of having someone there. Without love, we aren't whole.
