Damn, I didn't really expect her to do down that route. But way to go! It seems to be working, even if we haven't seen a change in the affection meter yet
@Umesan
??? They've literally only met that once and you're judging the crown prince for that already? Of course he'll threaten to kill her; he doesn't know her and suspected her.
Kallisto will appear more in the future, maybe at least 10 more chapters. They'll get to know each other more there.
Not that I don't like Eclise tho. He's also cool....
