What are some of the best written books of a male character yearning written in the man’s POV?

I know Mr Darcy, Heathcliff are very good examples but I need books which have a phenomenal depiction of yearning written in the male character's POV.

It can be how much he needs or wants her/him. Or how much he misses them to the point of sounding pathetic.

Just give me some gut wrenching depictions of pining/yearning from male POV
