@KAddict yes like what happened to the patients and did the little girl die or get better because they just gave them a drug that lowered their thirst for blood and who were the guys at the end are they gonna actually find the true antidote? all these questions unanswered needs to be answered!
@EmilioTrevino I think it needs another too. There are still parts of the plot that I have questions about that were never answered, and they left it at a perfect spot to continue it.
I cried so hard when Hyun Woo died since I had grown very attached but your right that at least he left being happy.
