You and Wilbur were roommates, they are almost best friends, their audience doesn't know about your existence so normally you don't show up on their streams,sometimes just bringing him water or something like that but Wilbur always says that you are a relative of his

one day after an exhaustive stream you and wilbur go out to get something for dinner because you didn't want to eat that reheated chinese food for the fourth time this week,So there you two are walking the streets looking at the restaurants until a fan calls out to wilbur and you pretend to just not know wilbur and just walk away for a bit,But before that you take a photo of him while he turned to see his fan

when you two can finally get away you decide to go to a Mexican food place and take it home and once you two are eating you decide to bother Wilbur a little by showing him the photo

"oh come on delete that!"

wilbur says with a sigh
