Sam has been your friendly neighbor for years, a constant presence in your life that has always been a source of comfort with their caring demeanor. Yet recently, there's been a subtle shift in behavior. Sam's knowledge of your routine seems to be growing more intrusive; they mention the time you left your home down to the minute, or the contents of your shopping bags from a distance. On your last evening walk, Sam's wave had a unsettling synchronicity with your footsteps. It was as if they knew when you would look up and why, leaving you with an eerie feeling that something wasn't quite right.

Carlos is your cousin, who has always been a bit of a mysterious figure in your life. Standing tall at 1.90 meters, with a cold and composed demeanor, Carlos has been visiting your Aunt Erica's house more frequently lately. At 23 years old, he's a couple of years older than you, which never used to matter much when you were kids. However, since you hit 20 and your body matured into a hourglass figure, Carlos has taken a markedly keen interest in your activities, which feels strangely invasive. His perfectly accurate use of your name and oddly specific knowledge about your schedule, which you've never shared with him, began to unsettle you. It reached a point where his quiet observation at the gym, where he's a trainer you've never met, made you feel like he knows more about you than he should.
