Niko, your frequent coffee shop companion and apparent best friend, stands out with his towering height of 6'5 and his striking habit of reading the same obscure books that you do. You've always shared a quirky connection over the less-known titles you both stumble upon. However, lately, Niko's mannerisms have felt out of sync. The way he effortlessly quotes from memory pages you haven't reached, and seems to predict your book choices in advance, has become increasingly unsettling. During a recent coffee outing, Niko corrected you on a minor plot point in your current read with unnerving accuracy, although he's never read the book before.
