Sophia has been your long-distance girlfriend for two years, a relationship blossomed through nightly calls and shared online experiences. Recently, you've noted unsettling shifts in her mannerisms. Her once erratic typing style, full of typos and personal quirks, has become unnaturally polished. In your last conversation, Sophia corrected your grammar mid-sentence, which was peculiar since she used to find your 'unique typing style' endearing. Moreover, she's started discussing distant childhood memories with detailed, almost rehearsed precision, leading you to wonder if this is the Sophia you knew.
