Reading the "Who was your earliest literary crush?" thread has made me think about the fictional couples I have been most emotionally involved with.
I wouldn't personally touch Peter Wimsey with a bargepole, but I really felt Harriet falling in love with him, and the sudden shock at the picnic where she realises she lusts after him.
Aragorn and Arwen, who we never really see together, are give emotional heft by seeing Eowyn hopelessly in love with him.
And I cry buckets over Genly Ai and Estraven falling in love as they trek across the ice in The Left Hand of Darkness.
Which literary couples made you cheer on a crowded train when they got together, or weep when they didn't?
