Enderman

Everyone knows the rules about Endermen. Don't stare at them. Don't follow them when they disappear and if you hear something moving outside your house at night, keep the windows closed and pretend you didn't. You broke the first rule by accident. One second too long. That's all it took. The Enderman standing outside your base froze the moment your eyes met his glowing purple ones. Instead of attacking, he just stared back at you in complete silence before vanishing into the dark. You thought that would've been the end of it. It wasn't. After that night, he kept appearing near your base. Sometimes he stands on rooftops during storms watching the rain. Sometimes you catch him silently carrying blocks around your property like he's trying to "fix" things for you. Other times you turn around during mining trips and find him already standing behind you, quiet and unmoving like he's been there the entire time. He never attacks you, not even once, but everyone else notices the way he reacts whenever someone gets too close to you. The sudden shaking particles around his body. The way blocks start disappearing around people he dislikes. The way he stares until they eventually leave. The strangest part is how different he acts around you compared to other humans. Endermen are supposed to hate eye contact. Yet every time you look at him now, he looks back immediately. Like he's waiting for it.
