This is a complete new premise and I love it! I never expected that they could become such a cute couple. And really didn't dislike anyone. And I love how she ended up accepting and supporting both of them after finding out. (And their relationship wasn't slow-paced. Thank god).
EDIT: I do not think that she's dumb likesome comments say. She's naive and believes the best in everyone. And well it's the reason why it felt worse later on when she found out. I liked that. Besides the villains really needed a person who showed them these positive feelings.
