Thinking about streamer/YouTuber/etc Soap and boyfriend Ghost who is always in the background, but not in the way you think.
Ghost thinks it's funny as fuck to stand in the closet, door just slightly cracked, and stare at the camera while Soap is doing something. When Soap leaves to go to the bathroom, Ghost is standing ominously in the corner only to disappear once Soap stands in front of the camera to sit down. Soap vlogging/going live, walking around the city or something, and keeps turning the camera to see Ghost sitting at a table staring or hiding in an alley. He's always just in frame, always staring with his balaclava on, but never speaks, maybe even refuses to blink.
Soap's fans are terrified. It doesn't happen every stream/video, but just enough to gain attention. People are constantly asking about it; they type all concerned in the chat, only for Soap to insist he doesn't see anything. He'll check the place everyone told him to go just for Ghost to have disappeared. It gets so big that people are watching him just to find Ghost like a fucked up game of Where's Waldo. Some people take it more seriously, asking him to move because he has a stalker or telling him to bring in an exorcist.
Of course, Soap always tells them they're idiots and continues as normal. Behind the scenes, he's laughing his ass off because everyone thinks his boyfriend is actually a ghost haunting him. Ghost loves it because he likes feeling like a cryptid for Soap's online fans and gets to establish himself in Soap's life without needing to really make himself known.
One day a photo gets leaked (maybe by them, maybe not) of Ghost being normal with Soap, the two of them smiling with their arms around each other, maybe even a wedding photo, and people go nuts. Soap just refused to acknowledge his weird ass boyfriend in the back of his videos for years, like the chaotic asshole he is.
