ROWOON looked at Wook coldly.
Minju left early because she had a photoshoot. Before her girlfried left, she hugged the doppelganger goodbye.
And he noticed that Wook whispered something in Minju's ear.
"What did you say to Minju earlier?" Rowoon asked while he and Wook were waiting for Yujin in the living room. "And why do you keep on approaching her? Your soul is different from a normal person, Wook. You might affect Minju negatively since she has a weak constitution. I'll appreciate it if you put a distance between you and my girlfriend."
"That will be difficult, Rowoonie," Wook said playfully. "Minjunnie and I are friends. I'm sure that my energy won't harm her, so don't worry too much."
To be fair, he knew that Wook's energy didn't harm his girlfriend.
He only used that as an excuse to separate the two because he wasn't comfortable seeing them get closer.
