Julian has been your closest confidant for years, always lifting your spirits with his boundless energy and infectious charm. Recently, however, your interactions have been marred by an unsettling feeling. His towering height, striking good looks, and usually warm demeanor have become almost too perfect. On the surface, everything seems fine, but the way he now holds your gaze for just a moment too long or his strangely mechanical compliments about your looks makes you question if you truly know him. The final straw came when, amidst a casual conversation, he recited a random fact about ketosis in your flatmate's voice, yet he has never shown any interest in the keto diet.
