*sparkles at you* Thank you very much! Yamamoto is so very complicated as a character, both straightforward and not. I tend not to think that his service to Tsuna is killing him inside, exactly, but that he is strangely willing to throw himself into his chosen causes. I think this fic is about him coming to adulthood, and an adult understanding of how to balance his causes and his own needs.

On top of being about grief and loss, too. *pats him* Poor guy.
