In Hades II, one of your romance options is Eris Goddess of Discord (not the chat platform).
Here she is playing hard to get.
Anyway, after countless hours of grinding, several gifts of nectar and ambrosia, and regularly beating the snot out of her (she's a level boss), she finally sweet talks the protagonist, Princess Melinoë, into going somewhere more private. Melinoë almost botches things by implying that she just wants to be friends, but in the end, you are given the choice to "Press A to Accept" Eris's offer of casual sex. Fade to black with mild sounds of female enjoyment. Achievement unlocked.
Next I'm going to try to woo Nemesis, Goddess of Vengeance.
