Three House of the Dragon partnerships make AO3's top 100 ships.

AO3 hosts fanfic, stories produced by fans about characters from popular TV shows, movies, games, etc. 

Whether they're items or not, these stories usually involve these people being busy.

Many Stranger Things fanfic authors imagine what might happen if Steve Harrington and Eddie Munson clashed. 

They "ship" in fanfic. Daemon and Rhaenyra Targaryen's inclusion is expected. 

Rhaenyra and Alicent Hightower's passionate love-hate relationship makes me expect them to be there. 

Aemond Targaryen with his nephew Lucerys Velaryon is surprising. 

Looking past the incest , their encounters mostly consisted of: 1) Lucerys slicing out Aemond's eye, and 2) Aemond killing both Lucerys and Arrax. 

In some fics, their hatred may turn to love.
