"You... you killed him!" a girl shrieked.
A crowd gathered around them, but before anyone could say anything, YuWon scoffed and kicked the corpse over. However, it wasn't a corpse but a... rag doll that rapidly faded away and turned to dust.
"What the—?" Yuna gasped, stepping back in shock.
She wasn't the only one. All of them were surprised except YuWon and a few of Joon's people.
"I killed him, right?" YuWon looked at Joon's people and smiled. "Do you mind explaining what this is, then?"
When 'Joon' touched his shoulder, the pendant told YuWon what was happening. Joon wasn't there, but he was controlling a puppet. It was his class. That's why YuWon didn't hold back and hit the puppet with all his strength.
The girls he had seen with the bald guy must have told Joon about him. He must have thought of YuWon as someone who could cause him trouble. That's why he orchestrated the act.
