I have a hard time believing he is gay lol. There was a post on reddit speculating that they're actually dating since they have been seen together a lot and they're both Hungarians living in the UK. Also the guy posts cars & racing stuff on instagram, that aren't really things a typical gay guy would be interested in. I'm also sure that everyone who mods for her does it for the sake of getting closer to her and try to build some relationship, they're romantically interested in her. Seems like just a convenient way of her keeping her community reassured about him.
Actually, he is gay; he always said it on Discord. In fact, there's a video of them climbing in Hungary, and even there he says he's gay. The guy's whole personality is based on being gay, and they say they don't know he's gay? On Discord, he would recount his sexual anecdotes, like his first time with a man and such. He never denied it; find that video, it's one where they're together doing rock climbing in a gym.
