Hm, I was just stalking your profile today haha and came across this piece. I'm always quite skeptical in reading love poems but this one was really well-written and I'm glad I did not skip this. The dedication added a spark to this poem; it added emotion and relatability. Again, the rhymes flowed really well. I love the diction you've used, really consistent all throughout, and it fit the Latin phrase you used.
I had a friend who died of cancer and whenever I read any poem about that, it really leaves me depressed. However, love was predominant in the atmosphere of this piece, so it has this hopeful tone to it, which I liked.
Sorry to hear about you grandfather. Hope all the best for him..
Keep writing :)
