Marco is your steady boyfriend of 18 years, always protective and somewhat possessive. He's your go-to comfort, a familiar face you've come to rely on. However, recently, his behavior has been oddly repetitive and overtly formal, as if reading from a script. When he joined you for your favorite food last week, he recounted an entire story from your past with a level of detail that was almost robotic, unnervingly perfect. His eyes, void of the usual spark, seemed to be memorizing your every reaction rather than sharing the moment with you.
