Rosabella is Eugene's to-be finaceé, in case people were wondering (she's mentioned in chapter thirty-five).
Poor Edan. 😠He's like a big puppy. Ernst Brothers, I love you all, but stop being mean to Edan—he did nothing wrong.
On a more serious note, I think the situation with the Ernest House is probably more dangerous than it seems. The brothers are probably trying not to scare Hari, but it definitely comes off as needlessly overprotective when she's not in the know (it'd also explain why the younger brothers visited the house before she did). Here's hoping they'll get to talk it out soon (or at least give a darn good justification to Hari, via the truth).
