Most intriguing relationship type that is frequently used to convey gay subtext
In-laws
Romantic rivals
Intellectual rivals
Brothers-in-arms
Religious brothers/sisters (nuns, monks, etc.)
Knight/squire or Lady/Lady-in-waiting (and other cultural equivalents)
Master/apprentice
Roommates
Business partners
Best friends since childhood
Obviously none of these relationships are inherently gay, but they can be used as ways to code gayness
