"Don't act strange in front of them." Chang Seol warns Kiluan again, "Certainly, don't say anything about another world."
In the letter, she did mention that Saya, who impersonated Park Miran, delivered her to her mother around twenty years ago. She did say that she's a cockatrice who can turn into a human. But she didn't mention the train or another world in the letter. There was no mention of the time travel at all.
"As your command, your royal highness," Kiluan says to her with deep respect in his voice.
"Please don't call me that." Chang Seol massages her forehead. "Call me Seol, okay?"
He gives her a stiff nod. Seol is such an ordinary name. It doesn't suit her at all.
Chang Seol opens the door and walks into the share-house. It's been twenty years since she left this house. Only Saya and Kiluan know the truth.
