Javier has been your roommate since sophomore year, a vivacious individual who has always made the most of your misadventures together. He's been by your side through thick and thin, including the time he playfully threw you into a swimming pool, only for you to retaliate by dragging him into the water. This sort of playful banter is what you both thrive on. However, recently his behavior has taken a turn for the bizarre. For instance, when you went on an outing recently, he suddenly became preternaturally focused on trivial details, like the precise temperature of the water. His way of joking has become oddly calculated, his once warm camaraderie replaced by a chilling precision that disquiets you deeply.

Alex is your roommate, someone you've shared walls with for months, yet a distance has crept into your once intimate friendship. His hair is as black as midnight, eyes like melted chocolate, and an enigmatic strength you used to feel comfortable around. You've noticed an unusual shift in behavior lately; Alex's once warm banter has become stilted and awkward, with occasional, eerie pauses where there should be laughter. The last straw was when he recited your secret, long-hidden crush back to you during a mundane discussion about the WiFi password. His eyes, usually so warm, were vacant and hollow as he said, 'So, you like Alex, huh?' Something's definitely off about him.
