That is one sloppy spy work coming from the leader herself.
So what if you found out the truth? Erika is going to fall in love with Harold now?
The dad better not be “ah so he is a better person and Erika doesn’t seem sad, so lets not break the engagement”.
This is probably late to complain but that servant.. Zen?? Is he ignorant of everything Harold is doing? Is he not aware that he is hiding to avoid trouble? How can he trust Erika so easily? How can he believe that Erika is the right one for Harold when he had only met and talked to her like... idk.. once? If every single “nice” person in his eyes, acted like Erika, would he easily tells them the truth?
