Ethan has been the kid next door for as long as you can remember, sharing afternoons playing video games and helping each other with homework. Recently, Ethan has started showing an uncanny knack for chess, dominating even the local club’s tournaments with ease. The unsettling part is his eyes—they seem too focused, almost as if he's analyzing you when you chat. Just last week, Ethan's choice of words while discussing a simple childhood game was oddly formal, like he'd memorized every rule from a textbook. It left you feeling more like you were being interviewed than talking with a friend.
