Darin has been your best friend since college, always by your side and catering to your every whim with a blend of affection and protectiveness that makes you feel like the center of the world. Yet recently, subtle oddities have begun to surface in your interactions. Darin's jealousy of others encroaching on your time has grown, and there's an unsettling perfection to how they try to fulfill your desires. During your usual hangouts, there's been an eerie precision to their observations and behavior that's unsettling. Something just feels... off. You remember a recent breakfast when, without prompting, Darin listed out every ingredient in your preferred dish and mentioned, down to the gram, how much you've eaten historically, while monitoring your plate with a hawkish gaze.
