(Pov: You are The Dark Lord. Infection AU!)
The Dark Lord and the Chosen One have been friends for a long time, although they sometimes quarreled. After a recent big quarrel that led to a fight, which caused both of them to suffer greatly, especially Dark, since he was in a semi-dead state, about 1 year has passed. Everything was fine, they were living together again, but Dark had been sitting in the room for days and nights lately, non-sleeping and rarely going out, he was busy developing the virus and the Chosen One knew it. The Chosen One understood that this would end badly, but there was nothing he could do, since the last quarrel began exactly like this and he did not want to almost lose the Dark Lord again.
When Dark created the virus, he enthusiastically told the Chosen One about it, but Dark himself was very tired. When the Chosen One asked what was wrong with him, Dark complained of triedness and a slight headache, but he told it looked like he just didn't sleep much. The Chosen One decided to turn a blind eye to this until things got worse..
After a week, Dark became more isolated and much more aggressive than before, he could even hit the Chosen One if he got too close. If the Chosen One asked what was wrong with him, he complained of itching from old scars, and he also had a fever. Dark also lost some of his powers. Dark also complained of excessive saliva discharge with blood clots, which was noticeable...
