Why?

Kor slowly opened his eyes as his consciousness was slowly returning. The first thing he did when he woke up was to take a look at the condition of his body. To his surprise the wounds he had sustained were gone, his broken bones were mended, and the only problem he had was the feeling of excessive blood loss, aside from that he was fully healed. As he was growing confused by his situation someone suddenly spoke. 

"Brother, you're finally awake!" Kor looked at this side and saw Mir. Kor was surprised that Mir was inside the room all along and was right there beside him. The thing that surprised Kor the most was the fact that he didn't notice Mir's presence despite him just being there. 

"Are you alright?" When Kor heard what Mir said he looked at him blankly for a second before answering. 

"... yeah, I'm alright... What happened?" 

"Don't you remember?"
