Well she's still at fault and both of them do look good together she told them the secret passage and her grandmother died and her lover is the one who killed her grandmother such a perfect match huh (I'm not talking about the fl)
So Romeo erased Juliet's memories about her first love..he replaced Juliet's memories that the man she love and who think he is different from the guy was him he's crazy.
She's treating our mc like she didn't even came here to prove herself that she's a daughter of the dukedom its obvious she doesn't want the truth to be exposed
