What’s a canon relationship the fandom just seems to entirely ignore?

Bugsnax, Lizbert x Eggabelle

They're canonically married, the whole point of the game is finding them, the main event that started the story was a marital dispute between them, the whole cast has dialogue referring to both of them and Egg waited for months on end on top of a mountain trying to figure out how to save Liz.

But them, and their relationship as a whole is mostly ignored by the fandom.
