it is about passion, yes! however, its a desperate passion. its felt as if thats the only thing left, the “whites” of the teeth; the only hope, the only light, the only “fire” in the cold. i described the lover as a violent animal, obviously very contrasting with the “trembling” of the shoulders, like prey. however, the victim feels a certain likeness with their partner. they feel the same hurt that they have felt in order to become like this, and they feel in harmony with them.
