Okie, so major spoiler alert:
Hayan runs and she sees yohan in some control room. She asks him why he betrayed her and killed her family. He says he used to believe that if you lived right, you would earn things through hard work. But he realised it wasn't true and the world was garbage. He was prepared to die, and that's when he met her parents.
He called them perfect beings. But he realised they weren't perfect either. When he ripped the dad's heart out, the dad's eyes looked very human because he was so shocked. He said the purebloods had softened because they lived with humans for so long. The mom died, so he couldn't get her heart, so Hayan is his last chance.
Anyways they clash physically and suddenly Hayan changes. Yohan is shocked. The next scene shows Eun Tae running to the control room. The room is shames and Hayan stands alone. She turns around and he gets a shock.
Yohan is in his car. His stomach has a massive injury. He tells his assistant that her dad had told him about this power purebloods have when they're super agitated. They will even turn on and murder their loved ones. That's what happened to their ancestor. Final scene is Hayan ripping through Eun Tae's body....don't know if he is okay.
Just finished 62. SPOILER:
For those of you who hate Yohan and want him to suffer by the hands of Hayan (tl;dr, everyone).... you are going to be very happy bois and girls
