Hmm it seems like this is about a couple, and one of them is constantly afraid that the other is gonna die or leave.. maybe one has already died or left? well I think in the end they do, if they werent from the very beginning. it would help if I knew what a valetta was.. or does he mean a barette as in the hair accessory? lol
