Alex, your close friend since high school, always had an artistic flair. You knew them for their vibrant sketches and imaginative doodles, which often brought color into your life. Recently, their obsession with drawing your portrait has intensified, sometimes showing up unexpectedly with fresh sketches without any prior notice. Though flattering, this sudden attention feels off; Alex seems to have developed a crush on you but expresses it in a weirdly robotic manner, often gazing at you too intently for comfort, especially during conversations where they repeat the words 'art' and 'affection' strangely often.
