My favorite couple in the interactive novel “Behind the Kalinov Bridge” 

In that story my Character lived in magic Slavic world and was smth as dragon slayer. He killed the dragons’ family, but could not kill the youngest baby of the dragon. He left him a scar. 
After that my character became a hero for people, but truly this murder was his big shame. Years has passed. During the game my character had adventures and in the end he met that baby dragon with scar. Now this baby grew up and was strong dragon, in his human form he was about 18 years old. Dragon wished for revenge. 
So there was a choice for my character: kill this dragon and be destroyed by destructive feeling of guiltiness  or give dragon the new family. (By ancient rule, instead of revenge, if you took the family from someone, you must give him the new one.) 
So my character has chosen to give him his youngest sister Olena as wife. Olena was not against. She did not want my character to feel guilty again and she was ready to become the wife for a dragon. 
And in epilogue there was information, that Olena and this Dragon-boy loved each other and were happy till the end of their days. Dragon loved Olena very very much. And they had big family. It is so sweet!
