"relished in the thoughts of been back,"
^ should this be "being back"?
Honestly, until the last stanza, I was for sure thinking this was about a person who chose to spend time with you, and over that time, grew to love and care for you. I really liked the personification of this book, a library book from what I could tell, and the kind of intimacy and emotional connection a reader and their book can have. It's cathartic, and what made this even more endearing was the perspective you wrote from. And I, too, have chosen something randomly, without really a second thought, only to be pleasantly surprised and moved by the way we can feel "nurtured" by a book, even one forgotten or left in dust!
I love this write, we can pair our love up with many different things and grow so attached, humans can love many things and people at the same time, what is discarded or abandoned by others we cane attach ourselves to it and create a bond, just a beautiful write
