If i had to choose.....
Probably anime/manga :)
Love those the most :D and i know these:

~ Attack on Titan
~ Black Butler
~ Card Captor Sakura

For if you want to continue with the pairings, i'll just add what i like most :D
Although... If we go with Black Butler... I would truelly enjoy being the butler :O If you don;t mind ofcourse... xD

~ Master x Servant/Slave
~ Hunter x Escaped Lap Experiment
~ Dragon x Human
