has there been any humans in a canon relationship that uses troll quadrants? i mean, normal human dating would probably be hearts. is there any human character who purposefully got in a relationship with diamonds/clubs/spades?

Rose tried to “clubs” between Gamzee and Terezi pre-retcon but it didn’t end up so well.

John’s also been doing a lot of Black flirting with TZ so stay tuned to find out if that happens
