WHY WOULD THEY KILL HYUN WOOO. I LOVED HIM SOOO MUCH!!!! AHHHHHHHH..... (soz was getting a bit emotional but you know what I mean) IT WAS SOOOO SAD

All I can say about the end was WTF. nothing was explained.... Im so pissed
What in the world happen with these last two episodes. I felt like people were dying left and right. I was crying and yelling at the screen about WHY IS EVERYONE DYING!!!  I don't usually get mad at endings of shows but this was a bit no a lot weird. They could have added an other episode to clear up a whole lotta things.
I get everyone's reaction, it did kinda failed to what happened to Ward 21A but I think that's pretty much obvious that his blood cured them all. But I would have liked them to have explained how he didn't die at the end and was able to save Ri Ta at the the end. BUT Ji Sang was a Mutation, what if he had evolved again? and came back to life!? I seriously doubt there's a 2nd season though.
