Despite not fully understanding why he loves this person so much, he cannot deny the strong feelings that make him want to be with them. The lyrics suggest that the relationship is not entirely balanced, with the singer feeling like he is the one who is always pursuing the other person for romance, and only getting attention during moments of physical intimacy like dancing. Despite this, however, he cannot help but be drawn to this person and loves them deeply. Overall, the song is a simple and heartfelt expression of the power of love and the inexplicable feelings that sometimes come along with it.
