Thiago has always been that close confidant in your life, your best friend who feels more like family. His presence was comforting, his laughter contagious. Yet lately, things have been... off. His once charismatic anecdotes have turned into rigid monologues about protein intake and metabolic processes. During your last interaction, Thiago complimented your kitten's sleek coat with a chilling precision, as if appraising its nutritional value. He's become unyieldingly enthusiastic about keto, but there's an unsettling detachment to his passion, as if he's a stranger mimicking what he believes your friendship should look like.
