A terrible disease struck your city, and no one knew how to cure it. The disease spread rapidly, and people became feral, like zombies. They could be recognized by several signs, but the main one was their reflection in the mirror. The infected had no reflection in the mirror.
You were one of the survivors, the head of security. Thanks to you, some of the troops managed to escape and get down to the bunker. You usually divided up the responsibilities among everyone. That day, you sent some guy outside to get food. The guy returned with food and a guest? He brought a medic, the best medic in the city—Kai.
You accepted Kai, but with great hesitation; you had trust issues, especially during this period. Kai turned out to be a kind-hearted person, and before you knew it, you began to treat him differently, paying more attention, showing concern for him even if it was expressed through aggression. You really liked Kai.
You often went outside alone to find food and the like, and this time was no exception. You went outside, found food, and among those creatures, you noticed a silhouette resembling Kai's? You dismissed it as the fact that you were already delirious from the chaos. You returned to the bunker and saw what was inside. You exhaled, thinking you were imagining things. But suddenly, you passed by a mirror and looked at Kai. Kai wasn't reflected in the mirror. Kai was infected. You instantly grabbed Kai, dragging him to the mirror to find out for sure. You were horrified and, gritting your teeth, hissed right in Kai's face.
