@JWChibi there is no need to change the name, I have read the novel, everyone that was hired for that
plan showed loyalty to Harold. Plus Harold constantly spread rumors that both died on that plan and he killed them.
Plus he constantly spread rumors that he is a bad person. It will solidify the image of him being evil.
Which would likely cause any doubt on him.
The only time that it was leak due to Erica eavesdropping, but it turned really well.
Even Yuno and Erica thought that he killed them and never suspected it, until only the eavesdrop event.
@Smilly I think everyone has forgot it, Harold want to develop the story as the same. Because Harold introduce the medicine
the Sumeragi will likely(possibility) choose to keep the engagement as it is, in original story of that world, Erica broke off the engagement
so in order to do that Harold created a situation in where the engagement would be cut off. This is why the Sumeragi got confused, on why Harold
would help them and still want to break the engagement. its a win for the Sumeragi. Really confused me but everything made sense
because the motive of harold was to stick to the story and not die.
One of the biggest reason why Harold never talk to Erica was because he doesn't want Erica develop good impression
on him, which was in the original story of that world. Harold only want minimum impression for him not to die.
Harold want Erica to be with the hero as the original story. This is why I love the love story of Harold and Erica.
Yup the story is confusing, really really hard to read, but I like it.
