I dislike straight mangas bc they make female characters indecisive, not developed, and I, like most girls, see myself as the female lead. Which is why I can't read them sometimes. Although I don't outright bash every female in yaois. Also you ignored the first two comments where the princess is harassing the dragon. That's why she's disliked.

Why do so many hate the princess so much already,,,? (⊙…⊙ ) She barely appeared yet ( ̄∇ ̄")
