Probably shock, who knows what kind of story is being spread. (Her friend got called an assassin before disappearing, now she's confronted with a witch that looks like a younger version of said friend)
"she is the apparition of a girl who had regrets and took on the form where she is happiest" kind of misunderstanding? Yep, I know enough stories for that
First of all, thank you so much for translating!! Also wow the pacing of this story is currently kind of strange - I can't seem to keep up with what's going on. But hopefully the plot will get clearer in upcoming chapters.
