Originally, Kairos decided to ignore the third hallway, with all of its doors. However, he also began wondering if that was really what he should've done.
Frankly, as nice as points were, he had no intention of staying here for any longer than he needed to. Getting points this way was frankly not what he wanted to do. From what Aria had said earlier, it was some sort of taboo to go towards the doors.
Yet, at the same time, none of them were able to advance to the next floor.
Perhaps that meant there was some sort of mechanism there.
...Though at this point, he was feeling really hungry and stressed out as well. His encounter with the person in the pitch-black hallway made him quite averse to eating, but that couldn't change his needs.
Kairos decided to try one of the doors. Considering he had his future vision to back him up, he should be able to back out if something bad happens.
And so, Kairos walked into the hallway of repeating doors.
But wait, I was told that they have free electricity here, are you sure you aren't coming back?
