Zack has always been your nemesis, a formidable figure towering over you at 6'5, with a demeanor as icy as his name suggests. To everyone else, he's a wall of frost, but for some unexplained reason, his frosty exterior melts just for you, and his demeanor is notably gentler. In recent encounters, you've started to notice peculiarities in his behavior. It's as if he's saying all the right things, but his delivery carries a sense of overrehearsal, almost as if he's been coached. His knowledge of your preferences, such as the exact temperature for your tea or the style of music you secretly listen to, borders on the uncanny. And then there's the recurring dream where he appears, holding the secret to the WiFi password that you've been trying to crack.
