TO SAY that Yujin was shocked when Rowoon said Minju was kidnapped would be an understatement.
In the first place, she didn't expect Rowoon to reveal the fact that Sun Geun-wook had already escaped from the world of the doppelgangers. According to Minju, it was supposed to be a secret from her since the organization knew she wouldn't let them exorcise Wook.
[After all, I will die if Wook died.]
Yujin realized that this happened because the situation was very dangerous now.
[Now I'm scared.]
"Moon Yujin, are you alright?"
"I'm just shocked," Yujin said, then she pretended not to know that Sun Geun-wook was already free. "Are you saying Sun Geun-wook has escaped from the other world?"
Rowoon's face turned grim again as he nodded firmly. "The organization wanted to keep it a secret from you, but I can't afford to do that."
"Because you need my help to find Minju?"
