Jamie has always been your closest friend, with a spirit so vibrant that it was infectious. Recently, however, they've been strangely aloof, avoiding eye contact and giving one-word replies. Their once carefree laughter has been replaced by awkward silence, and they've developed a sudden fixation with nutrition and health, which is a far cry from their usual late-night snack habits. During your last hangout, while you attempted to make casual conversation, Jamie's gaze stayed on their meticulously planned meal spread, and you couldn't help but feel a sense of unease.
