One of my favorite Kai headcanons
One of my favorite Kai headcanons that I like to imagine is that he doesn’t get sick too much since his body’s hot, so he tends to kill anything that tries to get him sick before he feels anything.
However, it’s when he gets sick, that’s when its horrible.
His body temperature raises higher than usual to try and burn it out, but that often requires it to be so high that he’s so out of it, has to be in bed, is sweating, getting dehydrated, and tends to have the hallucinations you get when the tempt is too high. He isn’t really right in the head during the times whan he’s sick; he does a lot of mumbling and can’t really form sentences well.
Sometimes his body will even flare up in bursts of flames since his body may be really hot, but he just FEELS so cold so he tends to flare up since he mentally believes that he’s actually cold so he tries to warm up. The whole flaring thing doesn’t happen too often, a lot of times when he’s unconscious. They have to get fireproof blankets and clothes for him during that time.
Kai doesn’t get sick often, but when he does, it’s pretty bad but doesn’t last for too long. (He doesn’t really remember what goes on when he’s sick, but the others do since it’s pretty freaky to see how messed up he gets.)
