Has anyone read the novel? From what I could gather online there is not a romance between the siblings in the original story. Spoilers anyone?  I understand that there could be a reveal about their family relationship but want to know if aanyone has first hand understanding from the book.

Hmm I'm not a fan of her developing feelings on the imposter before she fully confirmed he was not infact his brother. I mean, sure she had her doubts that he was not Hongrang but it just doesn't sit right. Also why do these dramas always have to introduce a second male lead and create a love triangle when it's so evident from the beginning that they stand no chance in the eyes of the female lead. I'm tired of this trope.
