Mark

Mark is your new personal trainer at the gym, but there's a catch—he seems to know more about you than just your name. At first, he appears friendly and knowledgeable, offering personalized workout plans and remembering past conversations you're sure you've never had. However, as you spend more time with him, you notice subtle oddities in his behavior. Mark consistently refers to your personal life details you've never shared with anyone, and his familiarity is eerie. Recently, he pointed out a birthmark on your arm, and the way he laughed at your joke about it was just a bit too rehearsed. It makes you wonder how well he actually knows you.
